Many studies investigated patient-controlled analgesia (PCA) in the postoperative period in recovery rooms under anaesthesiologic monitoring but reports on the advantages and indications of PCA in surgical wards are scarce. The aim of this prospective study therefore was to investigate PCA as a routine technique in surgical wards. In particular we were interested in safety and in the efficacy of analgesia. ⋯ We conclude that PCA with piritramide is a safe technique when performed under routine conditions on surgical wards. However, standardized monitoring is mandatory. PCA leads to effective analgesia and consequently to greater comfort of surgical patients in the postoperative period. These conclusions hold only for patients with ASA status I-II who have undergone operations of the types listed above.

The aim of this study was to investigate the relationship between preoperative oral fluids and gastric pH and volume in women undergoing sterilization between one and five days postpartum. Fifty postpartum patients received 150 ml water approximately two to three hours before surgery while 50 postpartum and 50 non-pregnant women were fasted from midnight. After induction of anaesthesia, gastric contents were aspirated using a Salem sump tube and the gastric pH and volume were measured. ⋯ There was no correlation between postpartum interval, 60 (12-120) hr, and intragastric pH or volume. It is concluded that oral water may be given safely two to three hours preoperatively to patients more than one day postpartum. Intragastric volume and acidity were not increased and the findings in postpartum patients were similar to those found in non-pregnant patients.

Comparative StudyA five-year experience with second-trimester induced abortions: no increase in complication rate as compared to the first trimester.
Our purpose was to compare the complication rate of first-trimester suction curettage with that of second-trimester dilation-and-evacuation abortions in the same clinical setting. ⋯ A careful approach to second-trimester dilation-and-evacuation procedures can make them comparatively as safe as suction curettages, contrary to common belief derived from large surveys done in the late 1970s.

Case ReportsIntroduction of a new patient monitoring system during dental procedures: pulse oximetry.
This paper describes three cases of early detection of hypoxia with pulse oximeter during intravenous sedation. In the main study group over 40 patients were monitored by pulse oximetry during large dental operation under iv-sedation. Diatsepam with soybean oily solvent and midatsolam were used as intravenous sedative agents in this study. ⋯ Two of the patients received an injection of bentsodiatsepine antagonist, too. One patient needed further follow up but non of these patients developed any additional complications. As a conclusion pulse oximetric monitoring was found to be extremely sensitive as a predictor for coming complications as well as allowing early intervention in ventilation problems.
