Assessment of postoperative pain: Contributing factors to the differences between patients and doctors.
This study was undertaken to compare the assessment of pain intensity by 50 patients and by their doctors according to a visual analog scale 5 h and 20 h after major abdominal surgery, and to examine the relationships between the differences in rating of patients and doctors and the factors inherent in the patients which include preoperative expectation of pain, level of anxiety, and the surgical history of the patient. The ratings given by the patients were significantly higher than those given by the doctors at both time periods. ⋯ The results of analysis using Hayashi's quantification theory Type II indicated a moderate association between the rating difference and the patient's age, surgical history, preoperative state of anxiety, and expectation of pain. It is concluded that postoperative pain management, whether in clinical practice or in research, necessitates more consideration of the several above-mentioned individual factors and a preoperative interview in which the patient's level of anxiety and the amount of information the patient has concerning the surgery and post-operative pain is clearly assessed.

The effect of prostaglandin E1 on the increase of serum lactate and plasma granulocyte elastase activity during radical surgery for esophageal cancer.
Serum lactate concentrations and the lactate/pyruvate (L/P) ratio were measured in two groups of patients undergoing radical esophagectomy, as an indicator of tissue hypoxia, and β-glucuronidase and granulocyte elastase as indicators of tissue damage. One group received prostaglandin E1 (PGE1) and the other group received nothing. Serum lactate concentrations and the L/P ratio increased significantly 30 min after starting thoracotomy in the patients who were not treated with PGE1. ⋯ There was no change in serum β-glucuronidase activity in both groups. This study suggests that low doses of PGE1 maintain organ blood flow without affecting blood pressure. However, these low doses of PGE1 could not suppress granulocyte elastase release.

There have been major advances in knowledge and efficient techniques for pain relief have been developed during recent years. Nevertheless, many patients on surgical wards still suffer from severe pain following surgery or trauma. Therefore, in the University hospital of Kiel (Germany) an anaesthesiology-based acute pain service (APS) was established in 1985 to improve this situation.

Norplant implants were removed from fifty (50) patients using a modified approach to Norplant implant removal (Emory Method). Eighty-eight percent (88%) of the removals were accomplished in less than 10 minutes using this technique. The average time for removal of Norplant implants from 50 women included in the current study was 8 minutes. ⋯ More anesthesia, a slightly longer incision and vigorous disruption of the tissue encapsulation surrounding the implants are recommended. The Emory Method is fast, safe and easy to perform. It has been successfully taught to over twenty-five clinicians.
