Risk factors for hospital and long-term mortality of critically ill elderly patients admitted to an intensive care unit.

BACKGROUND: Data on long-term outcomes of elderly (≥65 years) patients in ICU are sparse. MATERIALS AND METHODS: Adult patients (n = 1563, 45.4% elderly) admitted over 28 months were analyzed by competing risks regression model to determine independent factors related to in-hospital and long-term mortality. RESULTS: 414 (26.5%) and 337 (21.6%) patients died in-hospital and during the 52 months following discharge, respectively; the elderly group had higher mortality during both periods. After discharge, elderly patients had 2.3 times higher mortality compared to the general population of the same age-group. In-hospital mortality was independently associated with mechanical ventilation (subdistribution hazard ratio (SHR) 2.74), vasopressors (SHR 2.56), neurological disease (SHR 1.77), and Mortality Prediction Model II score (SHR 1.01) regardless of age and with malignancy (SHR, hematological 3.65, nonhematological 3.4) and prior renal replacement therapy (RRT, SHR 2.21) only in the elderly. Long-term mortality was associated with low hemoglobin concentration (SHR 0.94), airway disease (SHR 2.23), and malignancy (SHR hematological 1.11, nonhematological 2.31) regardless of age and with comorbidities especially among the nonelderly. CONCLUSIONS: Following discharge, elderly ICU patients have higher mortality compared to the nonelderly and general population. In the elderly group, prior RRT and malignancy contribute additionally to in-hospital mortality risk. In the long-term, comorbidities (age-related), anemia, airway disease, and malignancy were significantly associated with mortality.

Chronic abdominal pain in a Chinese woman with spastic cerebral palsy.

Pain affects people's activities of daily living especially among those with cerebral palsy. We report a case of a woman with spastic cerebral palsy who presented with chronic abdominal pain. The principles of multidisciplinary pain management are highlighted and the difficulties when dealing with patients with special needs are discussed.

Use of intrathecal morphine for postoperative pain relief after elective laparoscopic colorectal surgery.

Laparoscopic surgery has become popular in recent years, but few studies have addressed analgesia for this type of surgery. We conducted a prospective double-blind randomised trial on 36 cases of laparoscopic colorectal surgery to determine the influence of intrathecal morphine on postoperative pain relief. All patients received a subarachnoid block with local anaesthetic in addition to general anaesthesia. One group also received intrathecal morphine. A patient-controlled analgesic (PCA) device was prescribed for pain control postoperatively and the visual analogue score (VAS) was used for pain assessment. The group who received intrathecal morphine used significantly less morphine. There were no adverse cardiovascular effects of the combined anaesthetic technique. Nausea and vomiting remained the main side-effect of intrathecal morphine but this was easily treated with anti-emetics.

Outpatient laparoscopic cholecystectomy in Hong Kong: patient acceptance.

The authors performed a prospective evaluation of 60 Hong Kong Chinese patients with symptomatic gallstones and gallbladder polyps undergoing outpatient laparoscopic cholecystectomy in a regional hospital in Hong Kong from March 1996 to May 1998 to determine the feasibility, satisfaction, and acceptance of this procedure among Chinese patients. Patients with American Society of Anesthesiologists grade I and II gallstones or polyps were selected. Exclusion criteria included 1) history of upper abdominal operations, attacks of acute cholecystitis, cholangitis, or pancreatitis; 2) abnormal liver function; and 3) ultrasonographic evidence of contracted gallbladder, thickened gallbladder wall, dilated common bile duct, or common bile duct stones. Patients discharged at 5:00 PM on the day of cholecystectomy were defined as having undergone outpatient procedure. Patients were asked about procedure acceptance, rated on a scale of 1 to 10 (best), using a standardized questionnaire 4 weeks after operation. The study included 21 men and 39 women with mean age of 40.5 years (range, 27-59). There were no conversions to open procedures in the series. There were 6 (10%) unanticipated postoperative hospital admissions; all patients were discharged on the first postoperative day. Another patient was readmitted 3 days after operation because of a common bile duct stone. Overall patient acceptance of outpatient laparoscopic cholecystectomy was good, with a mean score of 8.6 of 10. Thirteen patients (22%) expressed dissatisfaction with being discharged earlier than they had expected, and 9 (15%) would have preferred inpatient care. Forty-eight patients (80%) resumed full daily activities by the first postoperative day; the remaining 12 did so by the end of the first week. Among the 44 working patients, only 4 (9%) resumed full duty within the first postoperative week; 29 (66%) did so by the second week and the remaining 11 (25%) returned to work after the third week. By selecting appropriate subjects, outpatient laparoscopic cholecystectomy is feasible and highly accepted among Hong Kong Chinese patients. Approximately one quarter of the patients preferred a longer postoperative stay or inpatient care.
