Incidence and severity of postoperative nausea and vomiting are similar after metoclopramide 20 mg and ondansetron 8 mg given by the end of laparoscopic cholecystectomies.

Background: Ondansetron has a well documented antiemetic prophylactic effect, whereas in most studies of postoperative nausea and vomiting (PONV), metoclopramide is less efficacious. This can be attributed to the short-lasting effect of metoclopramide when a low dose is given at the beginning of surgery. We wanted to test a 20-mg dose of metoclopramide given at the end of surgery, using ondansetron 8 mg as a reference.

Frequency and severity of headache after lumbar myelography using a 25-gauge pencil-point (Whitacre) spinal needle.

We studied 63 patients between the ages of 20 and 81 years undergoing lumbar myelography, using a 25-gauge pencil-point (Whitacre) spinal needle. With the use of a questionnaire, the incidence and severity of post-dural-puncture headache (PDPH) was investigated. There were three patients who complained of PDPH (4.

Classification and severity of postdural puncture headache. Comparison of 26-gauge and 27-gauge Quincke needle for spinal anaesthesia in day-care surgery in patients under 45 years.

Two hundred and five patients, aged 16-45 years, undergoing day care surgery were given a spinal anaesthetic using either a 26- or a 27-gauge Quincke point spinal needle. The occurrence of headache and accompanying symptoms postoperatively was analysed from 186 returned questionnaires. The incidence of classical postdural puncture headache was 4.

Spinal anaesthesia in day-care surgery with a 26-gauge needle.

We studied 106 day-care surgical patients (52 male) aged 18-70 yr (mean 49.6 yr) who received spinal anaesthesia with a 26-gauge spinal needle. The incidence of headache, back pain and patient acceptability were investigated after operation using a questionnaire.

Pharmacokinetics of i.v. and rectal methohexitone in children.

The pharmacokinetics of methohexitone were investigated in 15 healthy children undergoing minor surgery under inhalation anaesthesia. Six received 1% methohexitone 1-2 mg kg-1 i.v.
