Qualitative assessment of pain relief and functional improvement after coronary bypass surgery. A questionnaire survey among 527 patients

INTRODUCTION: We wanted to assess postoperative pain relief and functional improvement in all CABG patients (546) from Gentofte County Hospital (GCH) in 1997, so as to elicit better information on what to expect after CABG. MATERIAL AND METHODS: A descriptive cross-sectional survey, was carried out in 1999. All surviving patients (527) were sent a questionnaire with 17 questions in five categories: The course of the operation, pain level, medicine consumption postoperatively, working situation, and educational level. The inclusion criterion was CABG in GCH in 1997. RESULTS: One hundred and five women and 441 men (mean age 74 and 67 years) were entered. Response rate: 98%. Mortality rate: 0.9% in 30 days and 3.5% in two years. Sixty-four percent were satisfied with the course of the operation. In two years 33% were rehospitalised and 6% had a new CABG/PTCA. Other frequent diagnoses for readmission were AMI, arrhythmia, and angina. Considerable wound discomfort was reported by 21% (chest) and 13% (leg/arm). Marked pain relief and functional improvement was achieved postoperatively (95%). Postoperative angina was not associated with limitation in daily activities. Postoperative medicine consumption: 52% antihypertensives and 20% anti-angina medicine. The return-to-work rate, for those working before the operation was 75% in about two months, with a slight preponderance in those employed in the private sector. DISCUSSION: The study shows a high survival rate in two years after CABG. Considerable pain relief and functional improvement was achieved, and only a very small group derived no benefit from the operation. A large amount of patients had wound discomfort, which leaves an unsolved problem.

Evaluation of outcomes in patients following surgical treatment of chronic exertional compartment syndrome in the leg.

OBJECTIVE: To evaluate outcomes in patients who had a fasciotomy performed on their leg(s) for chronic exertional compartment syndrome (CECS). DESIGN: A retrospective descriptive cohort study. SETTING: Tertiary care sport medicine referral practice. PATIENTS: A consecutive series of 62 patients surgically treated for CECS from January 1991 to December 1997. MAIN OUTCOME MEASURES: A questionnaire was designed and developed to assess pain (using a 100 mm visual analogue scale), level of improvement, level of maximum activity, satisfaction level, and the occurrence of reoperations. RESULTS: Fifty patients had anterior/lateral compartment involvement, 8 patients had deep posterior compartment involvement, and 4 patients had anterior/lateral/deep posterior compartment involvement. The demographics of the 39 respondents and 23 nonrespondents were similar. The mean percent pain relief of respondents was 68% (95% CI [confidence interval] = 54% to 82%). There was no relationship between percent pain relief and the documented immediate post exercise compartment pressures. A clinically significant improvement was reported by 26 of 32 (81%) anterior/lateral compartment patients and 3 of 6 (50%) patients with deep posterior compartment involvement. Patient level of activity after fasciotomy was classified as equal to or higher than before the operation with a lesser degree of pain by 28 of 36 (78%) patients, while 8 of 36 (22%) patients reported lower activity levels than before the operation. Of the patients reporting lower activity, seven were due to exercise related pain in the post operative leg(s) and one was due to lifestyle changes. Thirty of 38 patients (79%) were satisfied with the outcome of the operation. Four of 62 patients (6%) failed the initial surgical procedure and required revision surgery for exercise-induced pain. In addition, one of these individuals also had a sympathectomy and another had a neurolysis performed at the time of revision surgery. Three of the 62 (5%) patients had subsequent operations for exercise-induced pain on different compartments than the initial surgical procedure. One individual had an unsuccessful operative repair of a posttraumatic neuroma. Postoperative complications were reported by 5 of 39 (13%) patients in the additional comments section of the questionnaire. CONCLUSIONS: The majority of patients surgically treated for CECS experience a high level of pain relief and are satisfied with the results of their operation. The level of pain relief experienced by patients is not related to the magnitude of the immediate post exercise compartment pressures. Despite the possibility that some patients have less favorable outcomes, experience complications, or need subsequent operations, fasciotomy is recommended for patients with CECS as there is no other treatment for this condition.

Palliative care education and training during residency: a survey among residents at a tertiary care hospital.

BACKGROUND: Palliative care is the active total care of patients in advanced and incurable stages of cancer. More than 70% of all cancer patients in India require palliative care for relief of pain, other symptoms and psychosocial distress. The need for education and training in palliative care has been emphasized by the World Health Organization (WHO) during the past 15 years. This survey aimed to assess the awareness, clinical knowledge, and education and training aspects of palliative care among the clinical residents of a tertiary care hospital. METHODS: During January and February 1999, a total of 100 residents were asked to respond to a questionnaire on palliative care education and training during residency. The questionnaire consisted of 10 questions (each question with 3 different responses). Awareness regarding palliative care was assessed by 3 questions; clinical knowledge by 4 questions; and education and training obtained during residency by 3 questions. Comparisons were made using the Chi-square test between the oncology and non-oncology resident groups. RESULTS: Forty-nine residents (23 oncology and 26 non-oncology) responded to the survey. Awareness that palliative care involves active total care was lacking in 8 (16%) residents. The cost of palliative care in India was considered high by 17 (65%) non-oncology residents and 21 (43%) of the whole group. Hospice, as the right place for palliative care, was chosen by 14 (61%) oncology and 3 (11.5%) non-oncology residents (p = 0.0003). In the whole group, 21 (43%) believed that palliative care could be provided on an outpatient basis. Pain, depression and cachexia were identified as the most distressing symptoms of patients with incurable cancer. Seventeen (83%) oncology and 4 (15%) non-oncology residents (p = 0.000) knew how to use the WHO step-ladder for cancer pain relief. All oncology residents and 10 (38%) non-oncology residents preferred the oral route for providing medications for pain relief (p = 0.0001). The didactic education and training imparted during residency was considered as 'not enough' by 39% of oncology and 62% of non-oncology residents (51% overall). The confidence to deliver quality palliative care was lacking in 43% and 58% of oncology and non-oncology residents, respectively. CONCLUSION: Clinicians in India need to be provided focused skills and training for them to be able deliver quality palliative care to the large number of patients with incurable cancer. The cost of palliative care and the optimum place to deliver it, the symptoms of advanced cancer, pain relief and symptom control methods and quality of life in end-stage cancer patients are some aspects that should be an integral part of clinical residency programmes.

Relief of refractory angina with continuous intravenous infusion of nitroglycerin.

Seventy-five patients with chest pain due to prolonged myocardial ischemia (group I, n=45) or acute myocardial infaction (group II, n=30) were treated with continuous intravenous infusion of nitroglycerin. pain relief was achieved immediately or after titration in 40 of 45 group I patients and 22 of 30 group II patients. Of the 29 group I patients who received narcotic analgesics for pain relief prior to the nitroglycerin infusion, 20 experienced a decrease in narcotics required for pain relief while intravenously receiving nitroglycerin. Twenty-four of 28 group I patients and 14 of 19 group II patients who had angina refractory to multiple doses of sublingual nitroglycerin received relief with intravenous administration of nitroglycerin. This data suggests that intravenous administration of nitroglycerin is useful, adjunctive therapy for chest pain even when refractory to multiple doses of sublingual nitroglycerin.

Patient expectations for pain relief in the ED.

The objective of the study was to assess patient expectations for pain relief in the ED. A convenience sample of 522 patients with pain and 144 patients without pain were enrolled in a prospective observational study at a university ED. Patients reported a mean expectation for pain relief of 72 % (95% CI 70-74). Eighteen percent expected complete (100%) pain relief in the ED. Patient expectations for pain relief were poorly correlated (r = 0.150) with initial pain intensity. Patients without pain reported a mean expectation for pain relief of 74% (95% CI 71-77) if they had presented with pain. There were no differences in patient expectations for pain relief based on age or gender. Patients expect a large percentage of their pain to be relieved in the ED, and many expect complete analgesia. Patient expectations for pain relief do not vary based on age, gender or pain intensity.

Long-term intrathecal infusion of morphine and morphine/bupivacaine mixtures in the treatment of cancer pain: a retrospective analysis of 51 cases.

A retrospective analysis of 51 patients with cancer pain treated with a continuous i.t. morphine infusion through a tunnelled percutaneous catheter was undertaken. Because of insufficient pain relief with morphine only, 17 of these patients received a morphine/bupivacaine mixture. pain relief subsequently improved significantly in 10 patients and a moderate improvement was present in 4 patients. An additional analgesic effect of bupivacaine was not shown in 3 patients with clinical signs of severe mental depression. Bupivacaine-induced side effects were absent below a daily dosage of 30 mg by continuous infusion. In all patients a gradual dose increment was observed. No serious complications, neurologic sequelae or meningitis occurred. It is concluded that long-term i.t. infusion of morphine through a tunnelled catheter can provide adequate pain relief in cancer patients with an acceptable risk-benefit ratio. The effects of long-term intrathecal co-administration of local anesthetics, especially bupivacaine, await further prospective evaluation.

Course and outcome of chronic pancreatitis. Longitudinal study of a mixed medical-surgical series of 245 patients.

Over the last 20 yr, 245 patients with chronic pancreatitis (163 with alcoholic relapsing pancreatitis; 145 of them with calcific pancreatitis) were prospectively studied at regular intervals with particular regard to pain, pancreatic functions, calcifications, pancreatic surgery, and survival. The median period of observation in the group with alcoholic relapsing calcific pancreatitis was 10.4 yr. In this group of 145 patients, 85% experienced lasting pain relief within a median time of 4.5 yr from onset. A gradual increase of pancreatic calcifications and pancreatic dysfunction was observed with increasing duration of the disease. pain relief was accompanied by a marked increase in pancreatic dysfunction and calcification. Of 163 patients with alcoholic relapsing pancreatitis, 87 (53%) needed no pancreatic surgery. Seventy-six patients (47%) with recurrent or persistent severe pain, mainly due to pseudocysts (n = 56), underwent either a cyst drainage procedure (n = 22), papillotomy (n = 4), distal pancreatectomy (40%-60%, n = 24), or Wirsungo-jejunostomy (n = 26). The proportion of patients experiencing lasting pain relief was similar in the operated and nonoperated group of patients. In both groups lasting relief from pain was correlated with the duration of the disease and was associated with marked pancreatic dysfunction. The 50% survival time in alcoholic chronic pancreatitis (with or without pancreatic surgery) was 20-24 yr (after onset), thus markedly shorter than in nonalcoholic pancreatitis. Of the 245 patients, 86 died. About 20% of deaths were related to pancreatitis and its complications. Most extrapancreatic causes of death were malignancies, cardiovascular diseases, severe infections, and nonpancreatic surgery.

Spinal cord stimulation in the treatment of paraplegic pain.

Twenty-five patients suffering from intractable pain due to a chronic spinal cord lesion underwent a percutaneous test of spinal cord stimulation. At the end of the test period, 40.9% of the patients reported a mean of 65% pain relief and these patients were selected for ongoing stimulation. At a mean follow-up time of 37.2 months the success rate, based on the number of patients with more than 50% pain relief, had fallen to 18.2%. pain relief rates were analyzed in relation to quality of pain, neurological status, level and extent of the lesion, and electrode level to identify prognostic factors that could improve the clinical usefulness of spinal cord stimulation. Patients experiencing painful spasms or a constrictive type of pain and with incomplete thoracic lesions were found to be the best candidates for spinal cord stimulation.

Long-term pain relief produced by intrathecal morphine infusion in 53 patients.

The present report details the characteristics of the analgesic effects of morphine administered chronically by infusion pumps implanted in 53 patients suffering from terminal metastatic disease. The median postimplant survival time in these patients was 4 months. Patients (mean age 58 years) were characterized according to the duration of pain before pump implantation (mean 16 months), prior consumption of systemic opioids (mean one to six daily analgesic equivalents of morphine), and their response to a trial intrathecal dose of morphine (1 to 2 mg). The median infusion dose at 2 weeks was 3.8 mg/day. The analgesic index, calculated as (quality of pain relief x duration of pain relief in hours)/morphine dose in mg, that was observed after the trial dose of morphine was determined for each patient. A close correlation was observed between the acute (2-week) infusion dose necessary to produce pain relief and the analgesic index such that the infusion dose = -8.0 x log (analgesic index) + 17.1. By 16 weeks, the mean spinal morphine dose for the group had increased by a factor of about 2.5; however, significant variation in the dose incrementation was documented. The maximum increase was observed in patients with a low analgesic index, and this rapid incrementation was usually correlated with an unsatisfactory overall outcome. Evidence that long-term infusion continues to yield analgesia was evidenced in six cases where there was an unanticipated loss of drug infusion and a corresponding increase in parenteral narcotic consumption. These data indicate the long-term efficacy and safety of spinal opioid infusion in patients with terminal cancer, and emphasize the advantage of assessing the sensitivity of the patient to spinal opioids by a standardized trial injection prior to pump placement as a prognostic indication of outcome.

Impact of laparoscopic surgery in the treatment of chronic abdominal pain syndrome

Chronic abdominal pain syndrome is becoming increasingly important with regard to the quality of life of the patients and its social and economic impact, in terms of cost of hospitalization, income loss due to sick leave, and pharmaceutical costs for treatments which fail to offer either significant clinical improvement or resolution of the pain symptoms. The main symptom is chronic abdominal pain, which may vary in intensity and may be associated with constipation and episodes of vomiting, when the clinical picture evolves toward one of subocclusion or total occlusion of the bowel. We considered the following criteria in our selection of patients for this study: 1) quality of life, 2) constant use of antispastic and analgesic medications, 3) absence of any other diagnosticable pathology prior to the operation. From August 1992 to April 2000 we operated on 105 patients with this syndrome (16 males and 89 females). Among these 8 patients had never been subjected to a laparotomy, while 97 had previously undergone surgical procedures (126 laparotomies). In the first 85 patients in the series (81%) we used a 10 mm laparoscope (0-30 degrees) to evaluate the presence of abdominal-visceral adhesions based on the type of surgery the patient had undergone previously, as well as the location of the pain reported by the patient. In 41 cases (48.2%) the pneumoperitoneum was obtained with the Veress needle. In another 44 cases (51.8%) the Hasson technique was used. Since June 1999, we have carried out the exploration of the abdominal cavity in 20 patients (19%) using a trocar and 2.2 mm laparoscope in the left hypochondrium along with a mini-trocar placed either in the right or left flank. (The positioning of the trocars depended on the previous surgical procedures performed). The exploration included inspection of the abdominal cavity. In 8 of the patients the procedure was carried out under local anaesthesia We performed laparoscopic adhesiolysis in 93 cases; in 7 cases no signs of adhesions were seen, while in another 5 cases it was necessary to convert the original laparoscopic procedure to a laparotomy. The types of adhesions found were fine-filmy (46%), dense-vascularised (46%), and cohesive (16%). In 6 cases during lysis of the adhesions complications of serous-muscular lesions occurred, which required laparotomic repair. In 5 cases we diagnosed a pathological condition which was not suspected. The average postoperative hospital stay was 2 days (range: 1-7); no major postoperative complications were noted. In the course of the follow-up of 78 patients over an average of 37 months (range: 6-72) the results obtained were as follows; 47 patients (60.2%) had complete pain relief, 18 patients (23.1%) had partial pain relief, and the remaining 13 patients (16.7%) had no significant pain relief. Laparoscopic exploration in patients with chronic abdominal pain is technically feasible in a simple manner in most patients. By means of careful and accurate preoperative selection of the patients partial if not complete pain relief can be achieved in a high percentage of cases (83.3% in our series).
