[The functional assessment of chronic pain patients activity of daily living and psychosocial disability].

The purpose of this study was to investigate the impact of activity of daily living and psychosocial function in patients with chronic nonmalignant pain. From Jun. 1989 to Nov. 1989, one hundred and eleven cases were assessed by Sickness Impact Profile (SIP) and Taita Symptom Check List (TSCL) to evaluate the disabilities associated with chronic pain. Patients showed significant impairment in the functions of physical psychosocial work and recreational activities. It was also apparent that the psychosocial disabilities were more severe than physical disabilities. Specifically, they showed anxiety depression and significant somatization. Analysis by stepwise multiple regression indicates that sex age educational level employment status diagnosis and pain intensity were the significant influencing factors related to the disabilities of activity of daily living and psychosocial function. The results supported the validity of the SIP as a measurement of functional status with chronic pain patients. Specifically, the psychosocial dimension was significantly correlated with the psychological and psychosocial distress categories of the TSCL. Based upon its reliability validity breadth of assessment and ease of administration, the SIP appeared to be well suited for the assessment of patients with chronic pain and for evaluating the efficacy of multidisciplinary pain treatment.

[The safety of geriatric anesthesia].

UNLABELLED: Perioperative abnormalities and complications were reviewed in 556 geriatric patients retrospectively to assess the safety of geriatric anesthesia. Preoperatively, the percentages of cases with cardiovascular and pulmonary abnormalities were 49.6% (276 cases) and 21.8% (121 cases) respectively. 77 percent of out patients (428 cases) were in the ASA class II physical status. The most common intraoperative complication was blood pressure instability and the incidence was noted to be of 34.8% (130 cases) with general anesthesia and of 15.8% (26 cases) with regional anesthesia. With general anesthesia, incidence for postoperative events such as non-fatal complications (i.e., sore throat and eye dryness), cardiovascular abnormalities and pulmonary disorders were found to be 39.0% (146 cases), 22.2% (83 cases) and 6.2% (23 cases) respectively. With regional anesthesia, the most common postoperative event was blood pressure instability (incidence: 21.2%, 35 cases). Total mortality rate of the first 15 postoperative days was 2.0% (11 cases). Mortality rate in elective and emergency surgery was 1.1% (5 cases) and 6.8% (6 cases) respectively. Causes of death were mainly related to illness deterioration (cancer and infection) or location of surgery. Death due to anesthetic mishap was nil in this study. IN CONCLUSION: Most geriatric patients had more than one system or one organ dysfunction before operation. Cardiovascular instability was the most common intraoperative complication. Postoperative mortality correlates closely with the preoperative ASA physical status. Mortality rate was significantly higher in emergency cases than in elective cases. A thorough pre-operative assessment and proper perioperative management are mandatory in geriatric anesthesia.

Halothane-inhalation system for using atracurium in rats.

This report describes an inhalation anesthetic technique employed in rats. Polyethylene-glycol 400 (PEG 400) was first designed to combine with halothane to produce a slow-releasing system of vaporized halothane. This design provided adequate anesthetic levels for treating with atracurium, a new neuromuscular blocking agent. Furthermore, isoflurane was also used in this study to examine this inhalation system for treating with atracurium. The efficient concentrations of inhalated anesthetics for adequate anesthesia when combining with PEG were 0.15% and 0.1% for halothane and isoflurane, respectively. This safe efficient state of anesthesia was maintained throughout the experimental course for treating atracurium, and might be used in clinical trials.
