Optimizing recovery after laparoscopic colon surgery (ORAL-CS)

BACKGROUND: The objective of this study was to determine if intravenous ketorolac can reduce ileus following laparoscopic colorectal surgery, thus shortening hospital stay. METHODS: This was a prospective, randomized, double-blind, placebo-controlled, clinical trial of patients undergoing laparoscopic colorectal resection and receiving morphine patient controlled analgesia (PCA) and either intravenous ketorolac (group A) or placebo (group B), for 48 h after surgery. Daily assessments were made by a blinded assistant for level of pain control. Diet advancement and discharge were decided according to strictly defined criteria. RESULTS: From October 2002 to March 2005, 190 patients underwent laparoscopic colorectal surgery. Of this total, 84 patients were eligible for this study and 70 consented. Another 26 patients were excluded, leaving 22 patients in each group. Two patients who suffered anastomotic leaks in the early postoperative period were excluded from further analysis. Median length of stay for the entire study was 4.0 days, with significant correlation between milligrams of morphine consumed and time to first flatus (r = 0.422, p = 0.005), full diet (r = 0.522, p < 0.001), and discharge (r = 0.437, p = 0.004). There we no differences between groups in age, body mass index, or operating time. Patients in group A consumed less morphine (33 +/- 31 mg versus 63 +/- 41 mg, p = 0.011), and had less time to first flatus (median 2.0 days versus 3.0 days, p < 0.001) and full diet (median 2.5 days versus 3.0 days, p = 0.033). The reduction in length of stay was not significant (mean 3.6 days versus 4.5 days, median 4.0 days versus 4.0 days, p = 0.142). Pain control was superior in group A. Three patients required readmission for treatment of five anastomotic leaks (4 in group A versus 1 in group B, p = 0.15). Two of them underwent reoperation. CONCLUSIONS: Intravenous ketorolac was efficacious in improving pain control and reducing postoperative ileus when anastomotic leaks were excluded. This simple intervention shows promise in reducing hospital stay, although the outcome was not statistically significant. The high number of leaks is inconsistent with this group's experience and is of concern.

Postoperative analgesia and recovery course after major colorectal surgery in elderly patients: a randomized comparison between intrathecal morphine and intravenous PCA morphine

BACKGROUND AND OBJECTIVES: Intrathecal morphine is a widely used method for postoperative pain relief after major abdominal surgery. The aim of this randomized, double-blinded study was to compare intrathecal morphine and intravenous PCA morphine for postoperative analgesia and recovery course after major colorectal surgery in elderly patients. METHODS: After written informed consent, patients >70 years of age were prospectively and randomly assigned to receive either preoperative intrathecal morphine (0.3 mg) and postoperative patient-controlled (PCA) intravenous morphine (IT morphine) or PCA alone (group control). Results are presented as mean +/- SD (95% confidence interval). RESULTS: Twenty-six patients successfully completed the study in each group. In the IT morphine group, rate of awakening was delayed. Pain intensity and daily intravenous morphine consumption were significantly reduced 1 and 2 days after surgery in the IT morphine group (P < .01). Mental function (assessed by Mini Mental State and Digit Symbol Substitution Test) was similar in both groups. Episodes of postoperative delirium/confusion occurred similarly in both groups. Time to ileus resolution and time to ambulation without assistance did not differ between the 2 groups. The duration of hospitalization was 8.4 +/- 1.7 (7-11) days and 7.9 +/- 2.0 (6-9.9) days for control and IT morphine, respectively (nonstatistical difference). Patients in the IT morphine group had longer time to awakening from anesthesia and experienced more sedation. CONCLUSIONS: Intrathecal morphine, as compared with intravenous PCA morphine alone, improves immediate postoperative pain and reduces parenteral morphine consumption but does not improve postoperative recovery in elderly patients after major colorectal surgery.     

The effect of epidural vs intravenous analgesia for posterior spinal fusion surgery

BACKGROUND: The study objective was to compare epidural vs intravenous postoperative analgesia in posterior spinal fusion surgery patients. METHODS: This prospective, double-blinded, randomized study was performed in a tertiary care teaching hospital involving 31 American Society of Anesthesiologists physical status I and II adolescent/young adult patients scheduled for elective posterior spinal fusion surgery for idiopathic scoliosis. Patients were divided into three treatment groups according to the epidural solution infused: group 1 (n = 10) 0.1% bupivacaine + 5 microg x ml(-1) fentanyl; group 2 (n = 12) 0.0625% bupivacaine + 5 microg x ml(-1) fentanyl; group 3 (n = 9) 0.9% sodium chloride (placebo). During general anesthesia all patients received a directly placed midthoracic epidural catheter with a set infusion rate followed by morphine sulfate intravenous patient-controlled analgesic device postoperatively. Morphine sulfate usage and visual analog scores were evaluated at 4 h intervals postoperatively for up to 96 h. Postoperative time to liquids, solid food, ambulation, length of stay, discontinuation of Foley catheter, and side effects were recorded. RESULTS: No consistent difference was detected on intravenous morphine dose usage, visual analog scores, or estimated pain scale over the whole follow-up period. No difference was observed in the epidural groups in time to oral intake of liquids or solids, ambulation, bowel sounds, or length of stay when compared with placebo. CONCLUSIONS: By evaluating morphine sulfate usage between groups, the analgesic effectiveness of continuous thoracic epidural analgesia bupivacaine and fentanyl doses used revealed no significant improvement over intravenous morphine sulfate analgesia alone in patients after posterior spinal fusion surgery.     

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.     

Local infiltration analgesia is not improved by postoperative intra-articular bolus injections for pain after total hip arthroplasty

Background and purpose — The effect of postoperative intra-articular bolus injections after total hip arthroplasty (THA) remains unclear. We tested the hypothesis that intra-articular bolus injections administered every 6 hours after surgery during the first 24 hours would significantly improve analgesia after THA.

Patients and methods — 80 patients undergoing THA received high-volume local infiltration analgesia (LIA; 200 mg ropivacaine and 30 mg ketorolac) followed by 4 intra-articular injections with either ropivacaine (100 mg) and ketorolac (15 mg) (the treatment group) or saline (the control group). The intra-articular injections were combined with 4 intravenous injections of either saline (treatment group) or 15 mg ketorolac (control group). All patients received morphine as patient-controlled analgesia (PCA). The primary outcome was consumption of intravenous morphine PCA and secondary outcomes were consumption of oral morphine, pain intensity, side effects, readiness for hospital discharge, length of hospital stay, and postoperative consumption of analgesics at 3, 6, and 12 weeks after surgery.

Results — There were no statistically significant differences between the 2 groups regarding postoperative consumption of intravenous morphine PCA. Postoperative pain scores during walking were higher in the treatment group from 24–72 hours after surgery, but other pain scores were similar between groups. Time to readiness for hospital discharge was longer in the treatment group. Other secondary outcomes were similar between groups.

Interpretation — Postoperative intra-articular bolus injections of ropivacaine and ketorolac cannot be recommended as analgesic method after THA.     

Does gum chewing reduce postoperative ileus following open colectomy for left‐sided colon and rectal cancer? – a prospective randomized controlled trial

OBJECTIVE: Postoperative ileus is common after colorectal resection and can prolong hospital stay. Gum chewing, a type of sham feeding, may to stimulate gut motility via cephalic-vagal stimulation, and thereby reduce the length of ileus. This study aimed to determine whether gum chewing in the immediate postoperative period facilitated recovery from ileus following resection for left-sided colorectal cancer. METHODS: In a prospective randomized control trial, 38 patients undergoing open surgery for left-sided colorectal cancer were allocated to standard postoperative care (control group, n = 19) or to standard postoperative care plus the immediate use of chewing gum (treatment group, n = 19). RESULT: Control patients passed flatus by mean of 2.7 days (SD 1.0) and faeces by 3.9 days (SD 1.5); for the treatment group, this was 2.4 days (SD 1.0) and 3.2 days (SD 1.5) respectively, (NS, P = 0.56 and P = 0.38). Length of hospital stay was 11.1 days (SD 7.3) in control group and 9.4 days (SD 2.5) in the treatment group (NS, P = 0.75). CONCLUSION: The addition of gum chewing to a standardized postoperative regimen did not reduce the period of postoperative ileus or shorten length of stay following open surgery for left-sided colorectal cancer.     

Effects of epidural bupivacaine and epidural morphine on bowel function and pain after hysterectomy

A comparison was made of the effects of continuous epidural analgesia with bupivacaine and intermittent epidural morphine on bowel function after abdominal hysterectomy. The duration of postoperative ileus was assessed as the time from the end of operation to the first postoperative passage of flatus and feces. Twenty-two patients were randomly allocated to two equal groups. An "epidural morphine" group received general anesthesia and epidural morphine for postoperative pain relief, and an "epidural bupivacaine" group was given combined general anesthesia and epidural anesthesia with 0.5% bupivacaine intraoperatively and epidural analgesia with 0.25% bupivacaine postoperatively. Epidural morphine or bupivacaine was given for 42 h postoperatively. Pain intensity (visual analog scale) was low in both groups, but lower (P less than 0.05) in the epidural bupivacaine group. The time to first passage of flatus was 22 +/- 16 h in the epidural bupivacaine group and 56 +/- 22 h in the epidural morphine group (P less than 0.001). The time to first postoperative passage of feces was shorter (P less than 0.05) in the former than in the latter 57 +/- 44 h vs 92 +/- 22 h). The patients of the epidural bupivacaine group started intake of oral fluids earlier (P less than 0.01) and to a greater extent (P less than 0.05) than those in the epidural morphine group. It is concluded that the duration of postoperative ileus after hysterectomy is shorter when epidural bupivacaine is given for postoperative pain relief than when this is achieved by epidural morphine.     

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.)     

Patient controllediv analgesia is an acceptable pain management strategy in morbidly obese patients undergoing gastric bypass surgery. A retrospective comparison with epidural analgesia

PURPOSE: To examine the hypothesis that pain treatment with patient controlled analgesia (PCA) using iv morphine is a suitable and safe alternative to epidural analgesia in morbidly obese patients undergoing gastric bypass surgery. We retrospectively compared the postoperative periods in all patients undergoing this procedure in our institution between November 1999 and November 2001. METHODS: According to their perioperative pain treatment, patients were assigned to a PCA group (with iv morphine) or an epidural analgesia group, in which patients received either intermittent doses of morphine or continuous infusions of bupivacaine/fentanyl. Study endpoints included quality of pain control, incidence of cardiovascular and respiratory complications, analgesia related side effects, time to ambulation and first flatus, length of hospital stay, and wound infections. RESULTS: Data from 86 patients were analyzed with 40 patients in the PCA group and 46 patients in the epidural group. Groups were similar with respect to age, body mass index, and gender. The type of analgesia did not affect the quality of pain control at rest, the frequency of nausea and pruritus, the time to ambulation and return of gastrointestinal function, and the length of hospital stay. Patients receiving epidural analgesia had a greater risk of wound infection than subjects with PCA (epidural group: 39%, PCA group: 15%, P = 0.01). CONCLUSION: We conclude that in grossly obese patients undergoing gastric bypass surgery PCA with iv morphine is an acceptable strategy for pain management and may confer some advantages when compared to epidural analgesia.     

Subjective and objective comparison of critical care pathways for open donor nephrectomy

PURPOSE: In the era of minimally invasive techniques and cost containment, care pathways after donor nephrectomy are important. While open donor nephrectomy remains the established procedure, questions regarding the surgical approach, postoperative care and patient morbidity/dissatisfaction have surfaced. We compared results of standard and fast-track care pathways after donor nephrectomy. MATERIALS AND METHODS: Between January 1998 and August 1999, 60 patients underwent open donor nephrectomy. By surgeon preference, patients received either ketorolac only (31), ketorolac plus morphine spinal (17) or patient controlled anesthesia (12). Data related to surgery, hospital course and cost were reviewed. Patients were surveyed regarding return to daily activities and groups were statistically analyzed. RESULTS: The mean dose per patient was 183 (ketorolac only), 180 (ketorolac plus morphine spinal) and 69 (patient controlled analgesia) mg. Median hospital stay was 2 days for the fast-track pathways (ketorolac only, ketorolac plus morphine spinal) compared to 3 days for the patient controlled analgesia group (p <0.001). Delayed oral intake was seen in 6% of patients on ketorolac only and 3% for those on ketorolac plus morphine spinal compared to 83% of the patient controlled analgesia group (p <0.001). Return to exercise (median weeks, p <0.79) was 2 for the ketorolac only group, 3.5 for ketorolac plus morphine spinal and 3.5 for patient controlled analgesia. Mean global cost was $9,394 for the ketorolac only group, $9,238 for ketorolac plus morphine spinal and $11,601 for patient controlled analgesia (p <0.02). CONCLUSIONS: Fast-track pathways significantly shortened hospital stay and quickened oral intake. Cost was significantly contained using new pathways. Resumption of daily activities was comparable among the groups. Comparisons of critical care pathways are required to optimize patient care after kidney donation. Prospective trials are needed to verify our results.     

Gum chewing enhances early recovery from postoperative ileus after laparoscopic colectomy

BACKGROUND: Postoperative ileus limits early hospital discharge for patients who have undergone laparoscopic procedures. Sham feeding has been reported to enhance bowel motility. Here, the effect of gum chewing is evaluated as a convenient method to enhance postoperative recovery from ileus after laparoscopic colectomy. STUDY DESIGN: A total of 19 patients who underwent elective laparoscopic colectomy for colorectal cancer participated in the study. Each patient was randomly assigned to one of two groups: a gum-chewing group (n = 10, mean age 58.6 years, range 50 to 71 years) or a control group (n = 9, mean age 60.6 years, range 45 to 80 years). The patients in the gum-chewing group chewed gum three times a day from the first postoperative AM until oral intake. The times of the first passage of flatus and defecation were recorded precisely. RESULTS: The first passage of flatus was seen, on average, on postoperative day 2.1 in the gum-chewing group and on day 3.2 in the control group (p < 0.01). The first defecation was 2.7 days sooner in the gum-chewing group (postoperative day 3.1) than in the control group (5.8 days; p< 0.01). All patients tolerated gum chewing on the first operative AM. The postoperative hospital stays for the gum-chewing and control groups were 13.5+/-3.0 days and 14.5+/-6.1 days, respectively. CONCLUSIONS: Gum chewing aids early recovery from postoperative ileus and is an inexpensive and physiologic method for stimulating bowel motility. Gum chewing should be added as an adjunct treatment in postoperative care because it might contribute to shorter hospital stays.     

Effect of sham feeding with gum chewing on postoperative ileus after liver transplantation—a randomized controlled trial

Postoperative ileus (POI) is a common complication after major abdominal surgery. Gum chewing has been shown to stimulate bowel motility and decrease duration of POI after abdominal surgery. We evaluated the effect of gum chewing in reducing the time to first flatus and on oral calorie intake in patients undergoing living or deceased donor liver transplantation. Patients were randomized into the sham feeding group or the control group. The sham feeding group chewed two pieces of xylitol flavored gum for 15 minutes, three times a day after extubation until oral nutrition was tolerated. The control group received the same routine care except for the gum chewing. Fifty‐nine patients were randomized into the sham feeding group (n=30) or the control group (n=29). There was no difference in the time to first flatus (72 [66.1‐82.9] hours vs 69.0 [57.6‐77.2] hours, P=.422). Cumulative energy intake (2.8 [5.8‐23.2] % vs 10.0 [8.5‐15.9] %, P=.695) and length of intensive care unit stay (4.2 [3.9‐5.3] days vs 4.0 [6.7‐4.5] days, P=.077) were also similar. In conclusion, sham feeding with gum chewing did not shorten the duration of POI nor facilitate oral intake after liver transplantation. (Clinicaltrials.gov number: NCT 01956643).     

Laparoscopy for colectomy accelerates restoration of bowel function when using patient controlled analgesia

PURPOSE: A standardized care plan incorporating patient-controlled analgesia with iv morphine and a non-accelerated feeding schedule following colectomy was used to compare return of bowel function and hospital discharge times following surgery done by laparoscopy or laparotomy METHODS: Thirty-eight patients were assigned to undergo either laparoscopic or laparotomy colon resection. Postoperative analgesia was achieved with patient-controlled analgesia with iv morphine. General anesthesia and perioperative care were standardized, and a traditional surgical and nursing care program was implemented. Gastrointestinal function (time from surgery to return of passage of flatus and presence of bowel movements), pain intensity (visual analogue scale) at rest, on coughing and on mobilization, amount of morphine used, and criteria for discharge and length of hospital stay were recorded. RESULTS: Bowel movements resumed earlier in the laparoscopic group (P < 0.05), but not passage of flatus. No significant relationship was found between the amount of morphine used and return of bowel function. Cumulative morphine consumption during the first two postoperative days was similar in both groups. Where a trend towards lower postoperative visual analogue scale scores was observed in the laparoscopic group, visual analogue scale scores on coughing were lower in the laparoscopic vs laparotomy group only during the first 24 hr (P < 0.05). Length of hospital stay was significantly shorter in the laparoscopic group (P < 0.05), although times to meet discharge criteria were similar in both groups. CONCLUSIONS: When patient-controlled analgesia with morphine and a traditional perioperative program are used, a laparoscopic approach to colon surgery promotes earlier restoration of bowel function and more rapid hospital discharge in comparison to resection by laparotomy.     

Addition of transversus abdominis plane block to patient controlled analgesia for laparoscopic high anterior resection improves analgesia,reduces opioid requirement and expedites recovery of bowel function

IntroductionOpioid sparing in postoperative pain management appears key in colorectal enhanced recovery. Transversus abdominis plane (TAP) blocks offer such an effect. This study aimed to quantify this effect on pain, opioid use and recovery of bowel function after laparoscopic high anterior resection.MethodsThis was a retrospective analysis of prospective data on 68 patients. Patients received an epidural (n=24), intravenous morphine patient controlled analgesia (PCA, n=22) or TAP blocks plus PCA (n=22) determined by anaesthetist preference. Outcome measures were numerical pain scores (0–3), cumulative intravenous morphine dose and time to recovery of bowel function (passage of flatus or stool).ResultsThere were no differences in patient characteristics, complications or extraction site. The TAP block group had lower pain scores (0.7 vs 1.36, p<0.001) and morphine requirements (8mg vs 15mg, p=0.01) than the group receiving PCA alone at 12 hours and 24 hours. Earlier passage of flatus (2.0 vs 2.7 vs 3.4 days, p=0.002), stool (3.1 vs 4.1 vs 5.5 days, p=0.04) and earlier discharge (4 vs 5 vs 6 days, p=0.02) were also seen.ConclusionsUse of TAP blocks was found to reduce pain and morphine use compared with PCA, expedite recovery of bowel function compared with PCA and epidural, and expedite hospital discharge compared with epidural.     

Randomized clinical trial comparing epidural anaesthesia and patient-controlled analgesia after laparoscopic segmental colectomy

BACKGROUND: This randomized clinical trial compared the use of thoracic epidural anaesthesia-analgesia (TEA) with morphine patient-controlled analgesia (PCA) for pain relief after laparoscopic colectomy. METHODS: Patients scheduled for segmental laparoscopic colectomy were randomized to receive TEA or PCA. Patients in the TEA group received bupivacaine and fentanyl before incision and after surgery by continuous infusion for 18 h. Patients in the PCA group self-administered morphine using an intravenous pump. The postoperative care plan was otherwise identical for the two groups. Postoperative pain was measured during ambulation using a visual analogue pain score. RESULTS: The study included 38 patients (18 TEA, 20 PCA), 16 of whom underwent right hemicolectomy or ileocolectomy and 22 sigmoid colectomy. Operating times, patient weight and distribution of American Society of Anesthesiologists grade were similar in the two groups. The mean(s.e.m.) total dose of drugs administered was 64(41) mg morphine in the PCA group, and 79(42) mg bupivacaine and 205(140) micro g fentanyl in the TEA group. Postoperative pain scores were significantly better in the TEA group at 6 h (mean(s.e.m.) 2.2(0.4) versus 6.6(0.5) with PCA; P = 0.001) and 18 h (2.2(0.3) versus 4.0(0.4); P = 0.003). Hospital stay was similar in the two groups. CONCLUSION: TEA significantly improved early analgesia following laparoscopic colectomy but did not affect the length of hospital stay.     

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.

Expediting return of bowel function after colorectal surgery

BackgroundPostoperative ileus is the main determinant of the length of hospital stay after colorectal surgery. Our objective was to analyze modifiable factors, including polyethylene glycol administration, associated with the return of bowel function.MethodsA retrospective review of all patients who underwent elective open partial colectomy from 2004 to 2006 at a single institution.ResultsThe time to the first bowel movement with and without oral intake within 48 hours postoperatively was 76 hours versus 134 hours (P < .001); with and without polyethylene glycol administration it was 73 hours versus 94 hours (P = .001); and with and without frequent ambulation it was 78 hours versus 95 hours (P = .012). With postoperative nasogastric tube drainage, the time to the first bowel movement was 22 hours longer (P = .002).ConclusionsThese data confirm previous findings supporting no nasogastric tube drainage, early feeding, and frequent ambulation after colorectal surgery. Additionally, our data suggest a strong association (P = .001) between the use of polyethylene glycol and the early return of bowel function.     

The influence of timing and route of administration of intravenous ketorolac on analgesia after hand surgery

A double-blind clinical trial was conducted on 47 patients scheduled for hand surgery under general anaesthesia to determine whether ketorolac given as part of an intravenous regional anaesthesia technique could provide better postoperative analgesia than ketorolac given intravenously either before or after surgery. Patients were randomly allocated to one of three groups to receive ketorolac 20 mg: intravenously in the non-operative arm before surgery (systemic presurgery group); intravenously to the operative arm after tourniquet inflation (regional presurgery group); intravenously in the non-operative arm after surgery (systemic postsurgery group). Postoperative pain scores were similar in the systemic presurgery and regional presurgery groups. The mean visual analogue summary pain score during the 24 h after surgery was 12.2 mm higher in the systemic postsurgery group than in the systemic presurgery group (95% CI: 0.8-23.7 mm, p = 0.037). There were no clinically important differences in mean postoperative visual analogue pain scores between the three study groups. There were no statistical differences in the mean postoperative morphine requirements between the three study groups. There is no benefit, in terms of improved postoperative analgesia, in giving ketorolac as an intravenous regional anaesthetic compared with systemic administration before surgery. The administration of ketorolac after surgery, rather then before, is not supported.
