A study was carried out to assess the effects of immediate postoperative oral rehydration in 51 unpremedicated women undergoing caesarean section under epidural anesthesia. The patients were randomly assigned to 2 groups: group 1 (n = 22)--fasting at least until 24 hours after the end of the operation, and group 2 (n = 29)--receiving immediate oral intake of fluids (water, tea or coffee with sugar) without limitation of quantity. The 2 groups were compared for the occurrence of postoperative nausea and vomiting, onset of peristalsis, rectal gas emission, first bowel movement, and possible complications. The results demonstrate no significant differences between the parturients who drank immediately postoperatively as compared to those in whom oral fluid intake was delayed for 24 hours or more. It is concluded that immediate postoperative oral rehydration had no harmful effect upon peristalsis post-caesarean section.

A 23-yr-old parturient with herpes gestationis spontaneously delivered a normal healthy infant under epidural analgesia. She received five injections of bupivacaine 0.5 per cent over a ten-hour period. There was no infection at the lumbar region, even though her body was covered with vesicles and bullae including the face and neck. Eight months after delivery the patient still has a vesicular eruption which occurs mainly during her menses.

The paratracheal audible respiratory monitor (PTARM) was assessed in anaesthetized patients who were not intubated. Its working principle is simple: the sound generated by the passage of air between the vocal cords is picked up by a microphone placed on the patient's neck; the electronic signal is then amplified and changed into an audible one. It can also be recorded. This monitor was compared to others already available, Transcor, which monitors breathing sounds using a stethoscope as transducer, and Thermistor, which monitors the changes in air temperature due to air movement during breathing. The PTARM does not tie the anaesthetist down to the patient's bed, as do the precordial or oesophageal stethoscopes. Its usefulness in detecting aspiration is under investigation. It is a reliable, noninvasive and cheap breath-to-breath respiratory monitor, which can also be used in intubated patients.
