Thoracic epidural analgesia facilitates the restoration of bowel function and dietary intake in patients undergoing laparoscopic colon resection using a traditional, nonaccelerated, perioperative care program

Background This randomized trial compared thoracic epidural analgesia with patient-controlled analgesia (PCA) using morphine for laparoscopic colectomy in a traditional, nonaccelerated, perioperative care program. Methods In the study, 50 patients scheduled for elective laparoscopic colon resection were randomized to either PCA morphine (n = 25) or thoracic epidural analgesia with bupivacaine and fentanyl (n = 25). Both groups received general anesthesia and multimodal pain relief, which included naproxen and acetaminophen for as long as 4 postoperative days. Time until passage of gas and bowel movements, dietary intake, postoperative quality of analgesia, readiness for discharge, and length of hospital stay were recorded. Results Recovery of postoperative ileus occurred sooner in the epidural group (p < 0.005) by an average 1 to 2 days, and resumption of full diet was achieved earlier (p < 0.05). Intensity of pain during the first 2 postoperative days was significantly lower at rest, with coughing, and with walking in the epidural group (p < 0.005). Readiness for discharge and hospital length of stay (5 days) were otherwise similar in the two groups. Conclusions When a traditional perioperative care program is used for laparoscopic colectomy, thoracic epidural analgesia is superior to PCA in accelerating the return of bowel function and dietary intake, while providing better pain relief.     

Oral oxycodone hydrochloride versus epidural anaesthesia for pain control after radical retropubic prostatectomy

OBJECTIVE: To evaluate whether combined oral intake of paracetamol (4 x 1 g) + oxycodone hydrochloride (2x10 mg) is adequate and equivalent to epidural anaesthesia (EDA) with respect to postoperative pain control and postoperative mobilization after radical retropubic prostatectomy (RRP). MATERIAL AND METHODS: Forty consecutive patients scheduled for RRP were randomized to either: EDA with ropivacaine + paracetamol (4 x 1 g tablet) + injected or oral morphine on demand (EDA group); or infiltration of 25-40 ml of 0.25% bupivacaine into the wound + oxycodone hydrochloride (2 x 10 mg tablet) + paracetamol (4x1 g tablet) + injected or oral morphine on demand (OXY group). The groups were compared with respect to pain control determined by means of a visual analogue scale (VAS), time to free mobilization, hospital stay, complications, operation time and bleeding. RESULTS: Both analgesic regimens provided satisfactory analgesia, i.e. VAS scores remained significantly below 4 (p<0.0001). The EDA group experienced slightly less pain than the OXY group on the operation day but this was not significant: median VAS scores of 0.7 and 1.8, respectively (p=0.27). Median VAS scores during hospital stay were 1.7 in both treatment groups. VAS scores ranged from 0.1 to 3.3 and from 0.2 to 3.5 in the EDA and OXY groups, respectively. There was no significant difference in postoperative mobilization between the groups (p=0.06). The median duration of hospital stay was 3 nights in both groups. CONCLUSION: Postoperative pain control after RRP with oral oxycodone hydrochloride, paracetamol and extra morphine on demand is preferable to EDA when pain control as well as mobilization and costs are taken into account.     

Randomized controlled trial to examine the influence of thoracic epidural analgesia on postoperative ileus after laparoscopic sigmoid resection.

BACKGROUND: The aim of the study was to evaluate whether perioperative epidural analgesia had any effect on the duration of postoperative ileus after laparoscopic sigmoid resection. METHODS: Twenty patients were randomized to surgery either with (group 1; n = 10) or without (group 2; n = 10) thoracic epidural analgesia. The major endpoint of the study was the time to the first postoperative bowel movement. Secondary endpoints were the interval until oral feeding was tolerated, incidence of postoperative vomiting, postoperative analgesic consumption use of patient-controlled analgesia (PCA) until the fourth day after operation, subjective pain perception and the incidence of epidural-related side-effects. RESULTS: Age, sex and American Society of Anesthesiologists classification were similar in the two groups. The first bowel movement was documented after a median of 54 (95 per cent confidence interval 32-127) h in group 1 and 77 (31-99) h in group 2 (P = 0.8). Oral feeding without additional parenteral therapy was tolerated after 48 (40-64) h in group 1 and after 56 (48-64) h in group 2 (P = 0.6). Postoperative vomiting occurred in two patients from each group. During epidural therapy the use of PCA was lower in group 1 (0.30 (0.19-0.96) mg morphine per kg) than in group 2 (0.56 (0.37-0. 80) mg/kg) (P < 0.05). Postoperative pain perception during rest and while coughing was similar in both groups. Three patients experienced reversible side-effects of epidural therapy (motor deficit, two patients; bladder dysfunction, one). CONCLUSION: Perioperative thoracic epidural analgesia did not have a clinically relevant effect on the duration of postoperative ileus after laparoscopic sigmoid resection.     

Epidural analgesia enhances functional exercise capacity and health-related quality of life after colonic surgery: results of a randomized trial

BACKGROUND: Multimodal analgesia programs have been shown to decrease hospital stay, but it not clear which functions are restored after surgery. The objective of this study is to evaluate the impact of epidural anesthesia and analgesia on functional exercise capacity and health-related quality of life. METHODS: Sixty-four patients undergoing elective colonic resection were randomized to either patient-controlled analgesia with morphine or thoracic epidural analgesia with bupivacaine and fentanyl (epidural group). All patients in both groups received similar perioperative care and were offered the same amount of postoperative oral nutrition and assistance with mobilization. Primary outcome was functional exercise capacity as measured by the 6-min walking test, and secondary outcome was health-related quality of life, as measured by the SF-36 health survey. These were assessed before surgery and at 3 and 6 weeks after hospital discharge. Other variables measured in hospital included pain and fatigue visual analogue scale, bowel function, time out of bed, nutritional intake, complication rate, readiness for discharge, and length of hospital stay. RESULTS: Although the 6-min walking test and the SF-36 physical health component decreased in both groups at 3 and 6 weeks after surgery, the patient-controlled analgesia group experienced a significantly greater decrease at both times (P < 0.01). Patients in the epidural group had lower postoperative pain and fatigue scores, which allowed them to mobilize to a greater extent (P < 0.05) and eat more (P < 0.05). Length of hospital stay and incidence of complications were similar in both groups, although patients in the epidural group were ready to be discharged earlier. CONCLUSIONS: The superior quality of pain relief provided by epidural analgesia had a positive impact on out-of-bed mobilization, bowel function, and intake of food, with long-lasting effects on exercise capacity and health-related quality of life.     

Efficacy of Opioids in Preemptive Multimodal Analgesia for Total Knee Arthroplasty: A Prospective,Double-Blind,Placebo-Controlled,Randomized Trial

BackgroundPreemptive multimodal analgesia is a commonly used technique to control pain following total knee arthroplasty (TKA). This study aimed to evaluate the efficacy of pre-emptive opioids for pain management in patients who underwent TKA.MethodsIn this prospective, double-blind, placebo-controlled, randomized trial, 100 patients who underwent TKA at our hospital were randomized to the oxycodone or control group. At 2 hours before surgery, patients in the oxycodone group received 400 mg celecoxib, 150 mg pregabalin, and 10 mg extended-release oxycodone hydrochloride. Patients in the control group received 400 mg celecoxib, 150 mg pregabalin, and placebo. The primary outcome was postoperative consumption of morphine hydrochloride as rescue analgesia. Secondary outcomes were time to first rescue analgesia, postoperative pain assessed by the visual analogue scale, functional recovery assessed by range of knee motion and ambulation distance, time until hospital discharge, indicators of liver function, and complication rates.ResultsThe 2 groups were similar in mean postoperative 0 to 24 hour morphine consumption (11.4 mg for control versus 12.4 mg for oxycodone group, P = .419) and mean total morphine consumption (18.2 versus 19.8 mg, P = .227). There were no statistical differences in secondary outcomes.ConclusionsIn our study, preemptive opioid administration did not provide clinical benefits over placebo. Orthopaedic surgeons should consider not using pre-operative opioids in patients undergoing TKA.     

Postoperative pain management and outcome after surgery

Postoperative pain management aims not only to decrease pain intensity but also to increase patient comfort and to improve postoperative outcome. Better pain control is achieved through a multimodal combination of regional analgesic techniques and systemic administration of analgesic agents. To guarantee uneventful follow-up and unnecessary prolongation of hospital stay, it is important to avoid side-effects of analgesic agents, especially those of opioids which are dose-related, by decreasing opioid demand through combination with non-opioid agents. Epidural analgesia not only has the advantage of providing potent and effective analgesia but also of hastening recovery of bowel function and facilitating physiotherapy and rehabilitation. Unfortunately, a reduction in postoperative morbidity and mortality by epidural analgesia has not actually been demonstrated. Inclusion of postoperative pain treatment in a multimodal approach of patient rehabilitation may improve recovery and shorten hospital stay. Effective treatment of postoperative pain is also likely to prevent chronic pain syndrome after surgery, but further studies are needed to support this hypothesis.     

Epidural Analgesia Enhances Functional Exercise Capacity and Health-related Quality of Life after Colonic Surgery: Results of a Randomized Trial

Background: Multimodal analgesia programs have been shown to decrease hospital stay, but it not clear which functions are restored after surgery. The objective of this study is to evaluate the impact of epidural anesthesia and analgesia on functional exercise capacity and health-related quality of life.

Methods: Sixty-four patients undergoing elective colonic resection were randomized to either patient-controlled analgesia with morphine or thoracic epidural analgesia with bupivacaine and fentanyl (epidural group). All patients in both groups received similar perioperative care and were offered the same amount of postoperative oral nutrition and assistance with mobilization. Primary outcome was functional exercise capacity as measured by the 6-min walking test, and secondary outcome was health-related quality of life, as measured by the SF-36 health survey. These were assessed before surgery and at 3 and 6 weeks after hospital discharge. Other variables measured in hospital included pain and fatigue visual analogue scale, bowel function, time out of bed, nutritional intake, complication rate, readiness for discharge, and length of hospital stay.

Results: Although the 6-min walking test and the SF-36 physical health component decreased in both groups at 3 and 6 weeks after surgery, the patient-controlled analgesia group experienced a significantly greater decrease at both times (P < 0.01). Patients in the epidural group had lower postoperative pain and fatigue scores, which allowed them to mobilize to a greater extent (P < 0.05) and eat more (P < 0.05). Length of hospital stay and incidence of complications were similar in both groups, although patients in the epidural group were ready to be discharged earlier.     

Epidural analgesia compared with intravenous morphine patient-controlled analgesia: postoperative outcome measures after mastectomy with immediate TRAM flap breast reconstruction

BACKGROUND AND OBJECTIVES: Epidural analgesia has been shown to provide superior pain control compared with intravenous (IV) opioids after major surgical procedures. In this study, we compared the effect of epidural analgesia and IV morphine patient-controlled analgesia (PCA) on pain relief, duration of hospitalization, oral nutrition, ambulation, and side effects in patients undergoing a major surgical procedure (i.e., unilateral mastectomy with immediate transverse rectus abdominis musculocutaneous flap reconstruction). METHODS: Eighteen patients were prospectively randomized to receive either epidural analgesia or PCA during the postoperative period. The intensity of pain was assessed daily by a 100-mm visual analog scale. The total length of hospital stay, time to ambulation, and time to oral nutrition were recorded. RESULTS: The epidural group had significantly lower pain scores at 3 evaluation times through postoperative day number 4 (P < .05). The total length of hospitalization for the epidural group (median, 101 hours) was significantly less than the PCA group (median, 126 hours; P = .0498). The time to first ambulation, time to first bowel sounds, time to tolerating oral nutrition, incidence of nausea/vomiting or pruritus, and time to first flatus were not statistically different between the groups. CONCLUSIONS: These results show that epidural analgesia compared with PCA offered improved pain control after breast reconstruction with immediate transverse rectus abdominis musculocutaneous flap reconstruction. It also resulted in a 25-hour reduction in time of hospitalization.     

Hospital stay of 2 days after open sigmoidectomy with a multimodal rehabilitation programme

BACKGROUND: Hospital stay after colonic surgery is usually between 5 and 10 days, limiting factors being pain, ileus, organ dysfunction and fatigue. Single-modality intervention to reduce these factors with laparoscopic surgery usually requires a hospital stay of 5 days. This paper reports the results of a multimodal rehabilitation regimen after open sigmoidectomy. METHODS: Sixteen unselected patients scheduled for elective sigmoid resection (median age 71 years) underwent operation under combined spinal-epidural anaesthesia. After operation, epidural analgesia was continued for 48 h, with immediate oral nutrition and mobilization, and with planned discharge 2 days after surgery. RESULTS: The median postoperative hospital stay was 2 (range 2-6) days (48 h), patients being mobilized for a median of 5 h on the second postoperative day (24-48 h) and for 10 h on the third day (48-72 h). Within 48 h of operation 14 patients had an oral intake of 2000 ml or more and 15 had resumed defaecation. Fatigue and pain scores were low during the first 8-9 days after operation, with a median of 13 h of mobilization per day after discharge. There were no medical or surgical complications during 30 days of follow-up, except for two patients who suffered postspinal headache. CONCLUSION: Postoperative recovery after open colonic surgery may be accelerated by effective pain relief integrated into an accelerated rehabilitation programme.     

A comparison of ketorolac tromethamine/oxycodone versus patient-controlled analgesia with morphine in anterior cruciate ligament reconstruction patients

Effective postoperative analgesia with minimal side effects remains an important goal in enabling increasingly complex surgical procedures to be performed on an outpatient basis. In this study, we examined the efficacy of postoperative analgesia in 90 patients undergoing anterior cruciate ligament reconstruction using a patellar tendon autograft, with a 24-hour hospital stay. Patients were randomized to receive either intramuscular ketorolac supplemented by oral oxycodone, or intravenous morphine via patient-controlled analgesia (PCA) device, for postoperative analgesia. Patients were monitored for 2 hours in the recovery room, then every 4 hours until discharge, for the presence of complications of nausea, vomiting, urinary retention, pruritus, and dizziness. Pain was assessed using a visual analog scale (VAS) on the morning of postoperative day one. All patients were discharged by 24 hours after surgery. Ten (20%) of the patients receiving ketorolac/oxycodone versus 31 (79%) of those receiving PCA morphine experienced postoperative complications (P < .05). Postoperative nausea, vomiting, and urinary retention were each significantly more common in the PCA morphine group (P < .05). The incidence of pruritus and dizziness was low overall. There was no significant difference between groups in the severity of postoperative pain as assessed using a VAS. We conclude that ketorolac/oxycodone may provide comparable analgesia with fewer undesirable side effects than PCA morphine in patients undergoing anterior cruciate ligament reconstruction. Patients receiving ketorolac/oxymorphone may have a better quality recovery and more rapid discharge. (Arthroscopy 1998 Nov-Dec;14(8):816-9.)     

Outcomes after single injection caudal epidural versus continuous infusion epidural via caudal approach for postoperative analgesia in infants and children undergoing patent ductus arteriosus ligation

Adequate postoperative analgesia enhances deep breathing and minimizes respiratory complications after thoracotomy. This study compares postoperative outcomes after single injection caudal epidural vs continuous infusion epidural via caudal approach for postoperative analgesia in infants and children undergoing thoracotomy for patent ductus arteriosus (PDA) ligation. A retrospective chart review was performed for 27 children who had undergone PDA ligation. The children were divided into three groups. We compared patient demographics, surgical duration, anaesthesia duration, length of ICU stay, incidence of emesis requiring treatment, time required to establish regular oral intake, requirement for supplemental intravenous opioids during the first postoperative day, and length of hospital stay. For paediatric patients undergoing PDA ligation, postoperative analgesia with continuous infusion epidural via caudal approach produced shorter ICU stay, less occurrence of postoperative emesis, earlier oral intake, elimination of intravenous opioid supplementation, and shorter hospital stay compared with single injection caudal epidural techniques.     

Patient-controlled epidural analgesia (PCEA) for postoperative pain control after lumbar spine surgery

Spine surgery remains one of the most common procedures for patients with a wide variety of spine disorders. Postoperative pain after major spine surgery is moderate to severe. We retrospectively reviewed 245 medical records of adult patients undergoing major spine surgery who received either patient-controlled epidural analgesia based on local anesthetics and opioids or patient-controlled intravenous analgesia as postoperative pain management. Several outcomes were analyzed including pain intensity, opioid consumption, time to endotracheal extubation, the incidence of deep venous thrombosis, and length of stay in the hospital. We found that the use of patient-controlled epidural analgesia provided better postoperative analgesia [median (quartiles) verbal analog scale score of 4 (3, 5) vs. 5 (3, 6)] and decreased the amount of opioid consumption postoperatively [median of 0 mg (0, 3) vs. 35 mg (0, 150)] compared with patient-controlled intravenous analgesia. Also, a substantially higher number of patients in the patient-controlled intravenous group required opioids as rescue analgesia. Incidences of deep venous thrombosis, operating room extubation, and length of stay in the hospital were not associated with the analgesic technique. The results of this study suggest that the use of neuroaxial analgesia for the management of postoperative pain associated with major spine surgery may have some beneficial properties over intravenous analgesia. The use of a reduced amount of opioids by patients with epidural analgesia may be relevant because of potential fewer side effects mainly in elderly patients. Several limitations related to the retrospective nature of the study are described. Prospective randomized-controlled trials are needed to understand and elucidate the optimum regimen of postoperative pain management after major spine surgery.     

Effect of epidural analgesia on bowel function in laparoscopic colorectal surgery: a systematic review and meta-analysis

Purpose

Use of thoracic epidural analgesia (TEA) with local anesthetic and adjuncts, such as opioids, are cornerstones of ERAS (Enhanced Recovery After Surgery) and are considered to play a key role in recovery after colorectal surgery. However, its effect on bowel function may lead to prolong hospital stay and is still a matter of debate. The purpose of this systemic review was to assess whether epidural analgesia could have a detrimental effect on bowel function in laparoscopic colorectal surgery with a subsequent effect on hospital stay duration, leading to failure of ERAS in colorectal surgery.

Methods

A systematic review of randomized, controlled trials for the effect of epidural analgesia on laparoscopic colorectal surgery was performed. The effect on postoperative recovery was evaluated in terms of return of bowel function as the primary outcome, whereas length of stay (LOS), pain score on visual analogue scale, operative time, and incidence of postoperative complications and side-effects of analgesia were recorded as secondary outcomes.

Results

Six trials published between 1999 and 2011 were included in the final analysis. TEA significantly improves return of bowel function assessed by time to first bowel motion [WMD ?0.62 (?1.11, ?0.12) with Z = 2.43; P = 0.02, 95 % confidence interval (CI)], and pain scores [WMD ?1.23 (?2.4, ?0.07)] with Z = 2.07; P = 0.04, 95 % CI]. TEA did not influence duration of hospital stay [WMD ?0.47 (?1.55, 0.61)] with Z = 0.85 (P = 0.39, 95 % CI). No significant increase in operative time or side effects was associated with TEA.

Conclusions

Despite of some beneficial effect of epidural analgesia on return of bowel function and pain in laparoscopic surgery, it does not affect LOS, which is multifactorial.     

Efficacy and safety of controlled-release oxycodone and standard therapies for postoperative pain after knee or hip replacement.

BACKGROUND: Standard therapy (ST) for postoperative pain after knee and hip replacement at the Hamilton Health Sciences Henderson Hospital consists of epidural analgesia or patient-controlled analgesia for the first 48 hours, followed by oral or parenteral analgesics, or both, on an as-needed basis. We compared the efficacy and safety of scheduled controlled-release (CR) oxycodone hydrochloride (OxyContin; Purdue Pharma, Pickering, Ont.) and ST for postoperative pain 48 hours after primary knee and hip replacement. METHODS: In 2 separate 3-week studies of similar design, pain intensity, pain relief, length of hospital stay, analgesic use and side effects of CR oxycodone (n = 70) and ST (n = 101) were evaluated. In the CR oxycodone trial, a dose de-escalation protocol was used. RESULTS: At the time of discharge from hospital, patients in the CR oxycodone group recorded lower mean (and standard deviation) pain intensity scores than the ST group (20.2 [17.9] v. 27.7 [21.5] mm on a 100-mm visual analogue scale; p = 0.021). Length of hospital stay was 5.5 and 6.4 days for the CR oxycodone and ST groups respectively (p < 0.001). CR oxycodone patients used less opioid (morphine equivalent) while in hospital than ST patients (p < 0.001), and the average number of daily administrations of analgesics in hospital was 2.1 and 3.5 for CR oxycodone and ST patients respectively (p < 0.001). ST patients reported more nausea and vomiting, pruritus and fever than the CR oxycodone patients, but less somnolence, constipation, dizziness, confusion and tachycardia. CONCLUSIONS: CR oxycodone every 12 hours is as effective as ST in treating postoperative pain but length of hospital stay was shorter and analgesic administration in the hospital was used less frequently, providing potential hospital cost savings and reduced use of health care resources.     

A comparison of the effects of patient-controlled analgesia with intravenous opioids versus Epidural analgesia on recovery after surgery for idiopathic scoliosis

STUDY DESIGN: Epidural infusion was compared with standard patient-controlled analgesia (PCA) in 50 patients after surgical correction of adolescent idiopathic scoliosis with respect to certain postoperative parameters. OBJECTIVES: To compare postoperative parameters after posterior spinal instrumentation and fusion (PSIF) and to determine whether epidural infusion prolongs hospital stay or increases the risk of complications. SUMMARY OF BACKGROUND DATA: Patient-controlled analgesia and epidural infusion are both safe and effective in controlling postoperative pain after PSIF. One criticism of epidural infusion has been longer hospital stays. No study was found in the literature in which PCA was compared with epidural infusion. METHODS: The records of 50 consecutive patients who had undergone PSIF were reviewed. The epidural group consisted of 30 patients and the PCA group 20. Age, weight, degree of curve, and levels fused were evenly matched. Postoperative parameters including the day that each patient tolerated a full diet, day of independent ambulation, length of hospital stay, and pain control were compared. RESULTS: Pain control was comparable in each group. The epidural group tolerated a full diet earlier and on average were discharged 0.5 days sooner than the PCA group. Both differences are statistically significant. No significant complications were reported in either group. CONCLUSIONS: Epidural infusion of opioids with bupivacaine is safe and effective for controlling postoperative pain after PSIF without an increased complication rate when compared with PCA. In the current study, patients tolerated a full diet and were discharged from the hospital an average of 0.5 days earlier than PCA-treated patients.     

A systematic review of postoperative analgesia following laparoscopic colorectal surgery

Objective  The use of epidural analgesia is considered fundamental in Enhanced Recovery Protocols. However its value in the perioperative management of laparoscopic colorectal surgical patients is unclear and analgesic regimens vary. The aim of this systematic review was to examine the effects of various analgesic regimes on outcomes following laparoscopic colectomy.
Method  A systematic review of studies assessing analgesic regimes following laparoscopic colorectal resection was performed. The primary outcome of interest was length of hospital stay whilst the secondary outcomes included pain, time to tolerate a normal diet, return of bowel function and postoperative complications.
Results  Eight studies were identified, five of which compared epidural vs patient controlled analgesia/intra-venous morphine. There were no significant differences between the groups in terms of outcomes, except pain control which was superior in the epidural group. Spinal anaesthesia using intrathecal morphine in addition to local anaesthetic, and the use of nonsteroidal anti-inflammatory agents have also been shown to reduce postoperative pain.
Conclusion  There is a paucity of data assessing the benefits of postoperative analgesic regimes following laparoscopic colorectal surgery and none of the protocols were shown to be clearly superior. Further studies, including the assessment of spinal analgesia are required to determine the most appropriate analgesic regime following laparoscopic colorectal surgery.     

Double-masked Randomized Trial Comparing Alternate Combinations of Intraoperative Anesthesia and Postoperative Analgesia in Abdominal Aortic Surgery

Background : Improvement in patient outcome and reduced use of medical resources may result from using epidural anesthesia and analgesia as compared with general anesthesia and intravenous opioids, although the relative importance of intraoperative versus postoperative technique has not been studied. This prospective, double-masked, randomized clinical trial was designed to compare alternate combinations of intraoperative anesthesia and postoperative analgesia with respect to postoperative outcomes in patients undergoing surgery of the abdominal aorta.

Methods : One hundred sixty-eight patients undergoing surgery of the abdominal aorta were randomly assigned to receive either thoracic epidural anesthesia combined with a light general anesthesia or general anesthesia alone intraoperatively and either intravenous or epidural patient-controlled analgesia postoperatively (four treatment groups). Patient-controlled analgesia was continued for at least 72 h. Protocols were used to standardize perioperative medical management and to preserve masking intraoperatively and postoperatively. A uniform surveillance strategy was used for the identification of prospectively defined postoperative complications. Outcome evaluation included postoperative hospital length of stay, direct medical costs, selected postoperative morbidities, and postoperative recovery milestones.

Results : Length of stay and direct medical costs for patients surviving to discharge were similar among the four treatment groups. Postoperative outcomes were similar among the four treatment groups with respect to death, myocardial infarction, myocardial ischemia, reoperation, pneumonia, and renal failure. Epidural patient-controlled analgesia was associated with a significantly shorter time to extubation (P = 0.002). Times to intensive care unit discharge, ward admission, first bowel sounds, first flatus, tolerating clear liquids, tolerating regular diet, and independent ambulation were similar among the four treatment groups. Postoperative pain scores were also similar among the four treatment groups.     

Improved bowel function after gynecological surgery with epidural bupivacaine-fentanyl than bupivacaine-morphine infusion

PURPOSE: To compare postoperative gastrointestinal recovery between continuous epidural bupivacaine-fentanyl and bupivacaine-morphine. METHODS: In a blinded, randomized, prospective trial, 60 women undergoing surgery for gynecologic cancer were studied. Anesthesia was provided by a combined general/epidural (L2-3 catheter) technique without epidural opioids. Postoperative epidural analgesia was by continuous infusion of bupivacaine 0.1% with either morphine 0.05 mg x ml(-1) (BM) or fentanyl 5 microg x ml(-1) (BF). Visual Analogue Scale (VAS) scores for pain at rest and during movement, and the return of bowel function were collected for three days and the duration of hospitalization were noted. RESULTS: On POD-1, 18.5% of patients in the BM group had emesis compared with none in the BF group (P = 0.038) and fewer patients in the BM group tolerated clear oral fluids (11.1% BM vs 40.6% BF, P = 0.025). These differences became insignificant on POD-2 and 3. Median pain scores were comparable at rest and ranged from 10-20 in the BM group vs 0-20 in the BF group over the three days. Similarly, median pain scores with movement respectively ranged from 20-25 and 20-30 in the BF and BM groups. The mean duration of hospitalization was longer in the BM group (5.7 +/- 2.4) vs BF (4.5 +/- 1.2 days), P = 0.017. CONCLUSION: Epidural BM and BF provided equally effective postoperative analgesia at rest and during movement. Compared with BM, epidural BF is associated with less emesis and an increased ability to tolerate oral fluids on POD-1 and an overall shorter hospital stay.
