Reduction of post-operative morbidity following patient-controlled morphine

The present study examined the impact of two methods of pain management on recovery in 38 women undergoing hysterectomy. One group received IV morphine in the recovery room and IM morphine on the ward on a PRN basis (PRN group). In the other group, a loading dose of morphine 8 mg IV was given when the patient first complained of pain and patient-controlled IV morphine (PCA) was initiated and continued for 48 h (PCA group). Both groups received similar amounts of morphine overall, differently distributed over time. The PCA patients received 8 mg.h-1 in the recovery room (approximately 2.5 hrs) and less thereafter. The PRN patients received approximately 2 mg.h-1 for the entire 48-hr period. Pain control was better throughout convalescence and less variable across time with PCA management. Minute ventilation also recovered faster and by day four was 25 per cent above the preoperative baseline in the PCA group. In addition, oral temperature became normal one day earlier, ambulation recovered more rapidly and patients were discharged from hospital earlier. The data suggest that early treatment with relatively high, self-titrated morphine doses may alter the course of the metabolic response to surgery.     

Randomized clinical trial of local bupivacaine perfusion versus parenteral morphine infusion for pain relief after laparotomy

BACKGROUND: Opioids are often used to decrease pain following laparotomy but are associated with unwanted side-effects. The effectiveness of local perfusion of bupivacaine 0.5 per cent following laparotomy was studied. METHODS: A prospective randomized study involving patients undergoing laparotomy for major colorectal surgery using a left iliac fossa skin crease incision was undertaken. Patients were randomized to receive either intermittent intravenous morphine infusion on demand with patient-controlled analgesia (PCA group) or continuous wound perfusion of local bupivacaine 0.5 per cent for 60 h (LA group). RESULTS: Seventy patients were recruited, 35 in each group. Patient demographics, surgical and recovery variables and complications were comparable in the two groups. The wound lengths were similar (median 14 cm in both groups). There was no statistically significant difference in postoperative pain scores at rest and with movement between the two groups, except for pain scores at rest on the first postoperative day (P = 0.03). The median total amount of morphine used was significantly greater in the PCA group (median 38 versus 0 mg in the LA group; P < 0.001). CONCLUSION: Direct continuous local wound perfusion of bupivacaine 0.5 per cent is as effective as PCA for postoperative pain relief after laparotomy. It is a safe and feasible alternative to parenteral opioids.     

Intra-operative colonic irrigation in the management of left-sided large bowel emergencies

In a consecutive series of 93 patients who required emergency surgery for distal colonic lesions, 61 had primary bowel resection with immediate anastomosis after intra-operative antegrade colonic irrigation. The operative mortality was 8 per cent, anastomotic leakage rate 7 per cent and superficial wound infection occurred in 3 per cent of patients. The mean hospital stay was 13 days. Of the remaining 32 patients, 3 did not have a resection and 29 had a primary resection and end colostomy without anastomosis: bowel continuity was later restored in 17 of 28 survivors (61 per cent) but 11 (39 per cent) were left with a permanent colostomy. The hospital mortality in this group was 6 per cent, superficial wound infection rate 14 per cent and the mean hospital stay 26 days. The results of this study suggest that intra-operative colonic irrigation is an effective method enabling the surgeon to perform a primary anastomosis with reasonable safety after emergency resection of selected distal colonic lesions.     

Burn injury and management in Liberia

Burn care in developing countries remains a challenge. This paper reviews the acute burn care of 21 patients admitted during a 1-year period to a hospital in Liberia. Lack of supplies and education, coupled with the local belief system, reflect on patient management. The study population to falled 21 patients, ranging from 1 to 62 years of age. TBSA burns ranged from 2 to 60 per cent (mean 21 per cent), 61 per cent of patients were grafted. The time between burn and graft varied between 5 and 96 days (mean 29.8). Graft take varied between 40 and 100 per cent (mean 81 per cent). Of the grafted patients 66.6 per cent received blood (average 732 ml). At the time of presentation 61.9 per cent of patients had other illness. The average number of hospital days was 37.9 (range 2–76). The mortality rate was 14.2 per cent. When managing burns in a developing country, adaption of a simple, clearly defined method of treatment, together with education of the caregivers, is suggested. As in the developed world, however, prevention is the critical factor.     

Questionnaires on patient-controlled analgesia to the nursing staff in the surgical ward]

Thirty-one nurses in the surgical ward engaged in delivering postoperative analgesia using patient-controlled analgesia (PCA) were asked to complete questionnaires on postoperative analgesia and PCA. Ninety-seven per cent of respondents agreed that the postoperative analgesia is beneficial for postoperative recovery, and answered that the desirable goal in postoperative analgesia is "no pain at rest". Not only "pain at movement" or "pain on coughing", but also "decreased conscious level while analgesia is achieved" were selected as undesirable conditions during postoperative course. Although no one had learned the concept of PCA in their nursing schools, 94 per cent of respondents approved PCA as a method for postoperative analgesia. Seventy seven per cent responded that PCA is effective in the pain relief during position change, pulmonary physiotherapy and induced early ambulation. In addition, 65 per cent of respondents chose PCA as a method for postoperative analgesia when they receive thoraco-abdominal surgery. On the other hand, some problems on pain management using PCA, such as taking care of patients' ambulation with carrying a PCA pump, extra time for instruction of PCA and extra support for patients' psychological state were listed. In conclusion, these results suggest that PCA is accepted as an excellent method for postoperative analgesia among our nurses in the surgical ward, and education in postoperative pain management including PCA is required in nursing school as well as after graduation.     

Immediate and long-term outcomes after lateral pancreaticojejunostomy for chronic pancreatitis

Lateral pancreaticojejunostomy (LPJ) is the recommended surgical treatment of intractable pain from chronic pancreatitis (CP) with obstruction and ductal dilatation. This study evaluated the etiology, morbidity, mortality, hospital costs, and quality of life (QL) for patients with LPJ for CP. Medical records of 60 patients undergoing LPJ for CP between 1988 and 1996 were reviewed. Long-term QL was assessed by the Short Form 36 Health Survey and analyzed against control populations of patients who underwent pancreatic debridement for necrosis and patients with laparoscopic cholecystectomy for cholelithiasis. CP etiologies included 52 per cent alcoholic, 28 per cent idiopathic, 13 per cent pancreatic divisum, and 7 per cent familial pancreatitis. Peri- and postoperative morbidity and mortality were 25 and 0 per cent respectively. Average hospital cost was $13,530 with mean postoperative hospital stay of 12.1 days. Overall physical and mental QL were diminished compared with both the debridement group and cholecystectomy group with particular detriments in areas of physical role (P < 0.05), bodily pain (P < 0.001), social function (P < 0.001), and mental health (P < 0.001). We conclude that LPJ for CP is a relatively safe procedure with low morbidity and mortality but results in a significantly diminished long-term QL relative to other surgical patients with pancreatic or biliary disease. This difference prevails in both physical and mental aspects of health.     

Suicide attempted by burning: a 10-year study of self-immolation deaths

In a 10-year retrospective survey of 699 admissions to the Burns Centre of Verona, 31 patients (4.4 per cent) had self-inflicted burns. No sex difference was found, the mean age was 38 years, with 58 per cent of the patients in the 20–39-year age group. The mean burned surface area (BSA) was 41 per cent, and 12 patients (38,7 per cent) died: seven within the first 24 h. The other five patients died within 40 days (mean survival: 18 days). A large number of patients had a history of previous psychiatric treatment, six patients had previously attempted suicide. Four patients were drug addicts, three of whom were affected by AIDS and one had been HIV-positive for a long time. The patients had continuous psychiatric treatment during the long hospital stay. After discharge the patients were assigned to territorial staff for psychiatric treatment. Our experience shows that these patients have a higher mortality rate and they need constant psychiatric support, which can be useful in preventing further suicide attempts.     

Plain abdominal radiographs and acute abdominal pain

The records of all (5080) patients presenting to a district general hospital with acute abdominal pain over a 4-year period were examined. The contribution of abdominal radiographs to the assessment of patients with suspected appendicitis, urinary tract infection, and non-specific abdominal pain was evaluated, these conditions accounting for 48 per cent of patients with abdominal pain and 32 per cent of those with abdominal radiographs. Any positive information from these radiographs was less likely to be helpful than incidental or inconsistent (and hence potentially misleading). Because of this high 'false positive' rate it is suggested that if the initial diagnosis is suspected appendicitis, urinary tract infection, or non-specific abdominal pain, there is little value in the routine use of abdominal radiographs.     

A policy of early excision and grafting in elderly burn patients shortens the hospital stay and improves survival

Early excision and grafting of the burn wound appears to shorten the hospital stay and decrease mortality in children and adults. However, whether an early surgical approach is safe in elderly burn patients has not been resolved. To answer this question we carried out a prospective study of early surgery in 114 consecutive patients over the age of 50 years. Patients were generally operated on between post-burn days 2 and 5. The mean age of the patients was 68 years, with a burn size of 22 per cent, of which 13 per cent was full thickness skin loss. The mean hospital stay of the surviving patients was reduced by 40 per cent compared to national averages (P less than 0.001). The mortality rate for the entire group of patients was 17 per cent, with 2 deaths in the 65 patients with burns less than 20 per cent total body surface area (TBSA). Although the mortality rate for patients with burns greater than 20 per cent TBSA was 35 per cent, this was less than predicted (P less than 0.05). The improvement in survival appeared to be due to a decrease in the incidence of lethal burn wound infections.     

Resources for managing trauma in rural New South Wales, Australia

BACKGROUND: Trauma bypass is not always appropriate in the management of rural trauma because of the large distances and travel times. Rural hospitals in New South Wales, Australia are an essential component of the statewide integrated trauma system. The present study profiles the trauma resources of base hospitals in rural New South Wales. METHODS: A structured questionnaire, addressed to the 'Director, Emergency Department' was distributed to all rural base hospitals in New South Wales. Follow-up telephone interviews were administered to complete data collection. RESULTS: Fourteen hospitals were identified. General and orthopaedic surgeons provided trauma care in all hospitals. Forty-three per cent of hospitals had resident subspecialty surgeons. Fifty per cent of hospitals had a formal hospital trauma team. In the remaining hospitals, the most common reason (86%) stated for the absence of a formal trauma team was a lack of personnel to provide 24 h immediate response to all trauma presentations. Seventy-one per cent of hospitals are staffed by a single doctor after hours. All hospitals had 24 h access to plain radiography and blood products. 86% had 24 h access to ultrasound and computed tomography, although always on an 'on-call' basis after hours. All hospitals had the capability to maintain ventilated patients, averaging two ventilated beds per hospital. An average of two trauma patients per hospital per month is transferred to a larger institution. Sixty-four per cent of hospitals participated in a trauma retrievals for their surrounding areas. Seventy-one per cent of hospitals engaged in quality assurance activities regarding trauma outcomes. CONCLUSIONS: Formal responses to major trauma in rural base hospitals in New South Wales are often restricted by a lack of specialist medical personnel. Nevertheless, the majority of hospitals have the resources to manage major trauma.     

Audit of open cholecystectomy in a district general hospital.

This retrospective study audited all non-malignant biliary surgery carried out in a district general hospital between January 1985 and December 1990. Surgery was performed on 722 patients: 555 (77 per cent) were women and 167 (23 per cent) were men. The mean(s.d.) age of the patients was 49(16) years. Elective admissions accounted for 70 per cent of cases and 30 per cent were emergency admissions. Ultrasonography confirmed the diagnosis in 93 per cent of cases. An elective operation was performed in 542 patients and 180 patients underwent an urgent or emergency operation. Simple cholecystectomy was performed on 616 patients (85 per cent); 92 (13 per cent) also underwent common bile duct exploration and 14 (2 per cent) had an additional unrelated procedure. The mean(s.d.) hospital stay was 12.3(6.3) (range 4-34) days. There was one perioperative death. The general overall morbidity rate was 25 per cent and the procedure-related morbidity rate was 7 per cent. For simple cholecystectomy (n = 630) there were no deaths; the general morbidity rate was 15 per cent and the procedure-related rate was 3 per cent.     

Arthroscopic capsular release for idiopathic frozen shoulder with intra-articular injection and a controlled manipulation

INTRODUCTION

The aim of this prospective study was to assess the immediate and long-term effectiveness of arthroscopic capsular release in a large cohort of patients with a precise and isolated diagnosis of stage II idiopathic frozen shoulder.

METHODS

All patients underwent a preoperative evaluation. Patients with secondary frozen shoulder and those with concurrent pathology at arthroscopy were excluded. This left 136 patients with a stage II arthroscopically confirmed idiopathic frozen shoulder. At each postoperative attendance, a record was made of pain, function and range of motion. At 12 months, the Oxford shoulder score was calculated, and pain and range of motion were assessed.

RESULTS

Fifty per cent achieved good pain relief within a week and eighty per cent within six weeks of arthroscopic capsular release. The mean preoperative visual analogue scale pain score was 6.6 and the mean postoperative score was 1.0. The mean time to achieving good pain relief was 16 days following surgery. No patient could sleep through the night prior to surgery while 90% reported having a complete night’s sleep at a mean of 12 days after surgery. The mean postoperative Oxford shoulder score was 38/48 and the mean improvement was 19.2.

CONCLUSIONS

This large series demonstrates that arthroscopic capsular release is a safe procedure, with rapid improvement in pain and a marked improvement in range of motion.     

Randomized clinical trial of early laparoscopy in the management of acute non-specific abdominal pain

BACKGROUND: Abdominal pain of uncertain aetiology (non-specific abdominal pain; NSAP) is the commonest reason for emergency surgical admission. The aim of this study was to examine the role of early laparoscopy in the management of NSAP. METHODS: Some 120 patients, admitted between November 1995 and October 1998 with acute abdominal pain of uncertain aetiology, were randomized into two groups: group 1 had laparoscopy during the first 18 h of admission and group 2 had close observation, conventional investigation and surgical intervention if signs of peritonism developed. Outcome measures were diagnosis, operative procedures, duration of hospital stay, readmission rate, morbidity and death, patient satisfaction and total number of investigations performed. RESULTS: Median hospital stay was 2 (range 1-13) days in both groups (P = 0.87). A diagnosis was established in 48 (81 per cent) of 59 patients in group 1 compared with 22 (36 per cent) of 61 in group 2 (P < 0.0001). The morbidity rate was 14 (24 per cent) of 59 in group 1 and 19 (31 per cent) of 61 in group 2 (P = 0.3629). The readmission rate at a median follow-up of 21 (range 1-35) months was 17 (29 per cent) of 59 in group 1 compared with 20 (33 per cent) of 61 in group 2 (P = 0. 6375). Well-being scores improved from 134 on admission to 149 of 177 6 weeks later in group 1 (P = 0.007) and from 132 to 143 of 177 in group 2 (P = 0.089). CONCLUSION: Early laparoscopy provided a higher diagnostic accuracy and improved quality of life in patients with NSAP.     

Endoscopic transthoracic electrocautery of the sympathetic chain for palmar and axillary hyperhidrosis

Endoscopic transthoracic electrocautery of the sympathetic chain has been the preferred treatment for palmar or axillary hyperhidrosis in this unit since 1980. A retrospective study was carried out of the first 112 patients with case material derived from a postal questionnaire, chart review and outpatient assessment. Eighty-five patients undergoing bilateral transthoracic electrocautery who replied to the questionnaire (76 per cent response rate) form the basis of this study. There were 65 females and 20 males with a mean age of 24.3 years (range 15-40 years). The hands alone were affected in 20 patients (24 per cent), the axillae alone in 17 (20 per cent) and both areas in 48 (56 per cent). Mean hospital stay was 3.1 days (range 1-7 days). Outcome was assessed by 92 per cent of patients immediately after operation as 'very much improved' or 'moderately improved', and this assessment persisted in 85 per cent after a mean follow-up of 43 months (range 3-95 months). Cosmetic results were rated as satisfactory by 95 per cent. Apart from pain after operation, morbidity was limited to transient Horner's syndrome in three patients, surgical emphysema in three, and pneumothorax requiring a chest drain in one. A repeat procedure was needed in one patient because of an inadequate first operation. Some compensatory hyperhidrosis occurred in 54 (64 per cent) patients. As a minimally invasive procedure, endoscopic transthoracic electrocautery should be considered the treatment of choice for palmar and axillary hyperhidrosis.     

Popliteal artery trauma in a rural level I trauma center

Popliteal vascular trauma has historically been an urban phenomenon. We hypothesized that rural popliteal artery injury would result more often from blunt mechanisms of injury (MOI), have a longer time to operation, and result in a higher amputation rate. We retrospectively reviewed all cases of popliteal artery injury from December 1994 to May 2001 at our rural trauma center. Age, gender, Injury Severity Score (ISS), MOI, scene transport versus transfer from a referring hospital, time to operation, and operative times were studied. Significance was determined by Student's t test with a P value < or = 0.05. Thirty-two popliteal artery injuries were found. Blunt trauma accounted for 50 per cent of the injuries. Eighty-eight per cent of the patients were transferred from a referring hospital. Patients transported directly from the scene had a higher ISS. Longer operative times translated into an increased need for fasciotomy. The amputation rate was 19 per cent. This is the first attempt to delineate the specific nature of rural popliteal artery trauma. The amputation rate was not different between the two different MOI and was independent of the time to operation. Of those patients receiving an amputation 83 per cent were transferred from another hospital and despite a statistically lower ISS still required an amputation.     

General surgery at rural Tennessee hospitals: a survey of rural Tennessee hospital administrators

Rural communities face an impending surgical workforce crisis. The purpose of this study is to describe perceptions of rural Tennessee hospital administrators regarding the importance of surgical services to their hospitals. In collaboration with the Tennessee Hospital Association, we developed and administered a 13-item survey based on a recently published national survey to 80 rural Tennessee hospitals in August 2008. A total of 29 responses were received for an overall 36.3 per cent response rate. Over 44 per cent of rural surgeons were older than 50 years of age, and 27.6 per cent of hospitals reported they would lose at least one surgeon in the next 2 years. The responding hospitals reported losing 10.4 per cent of their surgical workforce in the preceding 2 years. Over 53 per cent were actively recruiting a general surgeon with an average time to recruit a surgeon of 11.8 months. Ninety-seven per cent stated that having a surgical program was very important to their financial viability with the mean and median reported revenue generated by a single general surgeon being $1.8 million and $1.4 million, respectively. Almost 11 per cent of the hospitals stated they would have to close if they lost surgical services. Although rural Tennessee hospitals face similar difficulties to national rural hospitals with regard to retaining and hiring surgeons, slightly more Tennessee hospitals (54 vs 36%) were actively attempting to recruit a general surgeon. The shortage of general surgeons is a threat to the accessibility of comprehensive hospital-based care for rural Tennesseans.     

Abdominal pain: a surgical audit of 1190 emergency admissions

In an audit of 1190 emergency admissions with abdominal pain (1166 patients) in a general surgical unit, the diagnosis was non-specific abdominal pain (NSAP) in 415 (35 per cent), acute appendicitis in 200 (17 per cent) and intestinal obstruction in 176 (15 per cent). The largest number of admissions occurred in the age groups 10-29 years (31 per cent) and 60-79 years (29 per cent). Surgical operations were performed in 551 patients (47 per cent) and there was a 16 per cent incidence of unnecessary appendicectomy (22 per cent in the age group 20-29 years). Fifty-one deaths resulted in a 30-day hospital mortality rate of 4.4 per cent and a perioperative mortality rate of 8 per cent. The mortality rate increased significantly in patients aged greater than or equal to 60 years, and patients aged 80-89 years had a perioperative mortality rate of 20 per cent. The causes of perioperative death included laparotomy for inoperable disease (28 per cent), ruptured abdominal aortic aneurysm (23 per cent), perforated peptic ulcer (16 per cent) and colonic resections (14 per cent). The perioperative mortality rates for ruptured aneurysm and perforated ulcer were 71 and 23 per cent respectively. The duration of inpatient stay increased significantly with the age of the patients, including those with NSAP. The results of the study indicate a need to review the methods of management of ruptured aortic aneurysm and perforated peptic ulcer, the methods of diagnosis of appendicitis, particularly in young females, and the factors that determine the duration of stay of patients suffering from NSAP.     

Testicular torsion in the armed services: twelve year review of 179 cases

All cases of testicular torsion occurring in the Armed Services between 1972 and 1983 have been reviewed. All cases were post-pubertal. The incidence in older age groups is higher than previously reported. No cases were seen in undescended testes. No seasonal variation in presentation was detected. Recurrent scrotal pain before acute presentation occurred in 29 per cent of cases. The testicular salvage rate was 75 per cent. The salvage rate in patients with pain for greater than 24 h was 46 per cent. Patients with a history of intermittent scrotal pain should be explored as a matter of urgency. Operation should still be considered in patients who have had pain for greater than 24 h.     

Single-blind randomized clinical trial of laparoscopic versus open appendicectomy in children

BACKGROUND: Appendicectomy is the most common emergency surgical operation in children. The aim of this study was to compare recovery after appendicectomy using either a laparoscopic or an open technique in children. METHODS: Sixty-one children aged 4-15 years undergoing appendicectomy for suspected uncomplicated appendicitis were studied. The study was prospective, randomized and single-blinded, with parallel groups. Standardized anaesthetic technique and pain management were used. The study endpoints were postoperative pain, need for rescue analgesia, and length of hospital stay. RESULTS: Children had significantly less pain after laparoscopic compared with open appendicectomy 8 h after operation and on the first and second postoperative mornings (P < 0.05). Laparoscopic appendicectomy resulted in a reduced requirement for rescue analgesia with oxycodone in hospital: mean(s.d.) 3.6(2.5) versus 5.8(3.3) doses (mean difference 2.2 doses, 95 per cent confidence interval (c.i.) 0.6--3.8 doses); P = 0.01. The mean(s.d.) length of hospital stay was significantly shorter in the laparoscopic group: 1.9(0.7) versus 2.6(0.9) days (mean difference 0.7 days, 95 per cent c.i. 0.3--1.1 days); P = 0.001. Three children who had open appendicectomy developed a wound infection. CONCLUSION: Laparoscopic appendicectomy is associated with less postoperative pain and a shorter hospital stay than open appendicectomy in children undergoing surgery for uncomplicated appendicitis.
