This study investigates the effects of a primary nursing care delivery system on some work-related factors of nurses in long-stay psychiatric care settings. In a quasi-experimental research design a cohort of 176 nurses was followed for 2.5 years. Results showed that as a result of primary nursing the primary nurses found more autonomy in their work and(More)
A prospective, double-blind, randomized, controlled study was undertaken to compare the perioperative analgesic and recovery characteristics of equipotent doses of tramadol, pethidine and nalbuphine (3.0 mg kg-1, 1.5 mg kg-1 and 0.3 mg kg-1 respectively) with placebo (saline 0.02 ml kg-1) given at induction of anaesthesia in 152 ASA 1 children and young(More)
Data related to the incidence of postoperative vomiting were collected during prospective studies on 607 ophthalmic surgical patients of all ages who underwent halothane anaesthesia with spontaneous ventilation. Analysis of data in respect of age, sex and surgical site variables, and time of onset of vomiting, identified a female sex-related vomiting(More)
One hundred and sixty seven operating theatre personnel familiar with the practice of venous cannulation were asked to rank (in increasing order from one to five, corresponding to least to most painful) their opinion of the pain which they considered might accompany venous cannulation of each of five vein sites on the upper limb (dorsum of arm, dorsum of(More)
This study has compared the incidences of nausea, vomiting and headache after ondansetron 0.06 mg kg-1 i.v., prochlorperazine 0.2 mg kg-1 i.m. and prochlorperazine 0.1 mg kg-1 i.v. given during induction of general anaesthesia to 282 patients undergoing adenotonsillectomy. The cardiovascular effects of the drugs were similar. After operation, nausea per se(More)
If given a choice, would patients prefer an inhaled or IV method of inducing anesthesia? We investigated the choice between inhaled and IV induction of anesthesia of adult patients presenting to an academic institution for ambulatory surgery. Of 240 patients audited at the preoperative visit, 212 (88%) reported anesthetic histories in which anesthesia had(More)
The usefulness of intra-operative antiemetics and postoperative oral fluid restriction in the prevention of vomiting following anaesthesia for ophthalmic surgery, was studied in 200 patients. They were allocated into four groups of 50 and given either saline (as control), droperidol, metoclopramide or prochlorperazine. Oral intake was restricted(More)
A study was undertaken to compare the size of tracheal tube used for paediatric anaesthesia derived from either the diameter of the distal phalanx of the little or index finger, or from a standard formula (age in years/4 + 4.5 mm). The results showed that the diameter of the terminal phalanx was a poor predictor of the external diameter of the tube that(More)
The efficacy of peribulbar anaesthesia performed with short, medium and long needles, with sub-Tenon's injection as a control, was audited. Two hundred patients undergoing cataract surgery underwent peribulbar injection using 25G needles of the following lengths: 15 mm, 25 mm or 37.5 mm. Sub-Tenon's injections were performed with a curved 25-mm sub-Tenon(More)
