Sublingual glyceryl trinitrate for uterine relaxation at Caeserean section--a prospective trial.

We report a prospective study on the use of sublingual glyceryl trinitrate at Caesarean section to induce uterine relaxation; 23 women were entered into the study with both emergency and elective cases considered. A metered dose spray was used to deliver a dose of 400 or 800 microgrammes of glyceryl trinitrate to the women. There were no major side-effects of hypotension or postpartum haemorrhage. The mean maximal systolic blood pressure drop in the patients following drug administration was 18% of the systolic pressure prior to drug administration. Subjective assessment of uterine tone showed the uterus to contract well postdelivery in response to standard oxytocic regimens. Minimal maternal side-effects were reported. We conclude that glyceryl trinitrate is a safe form of uterine relaxation at Caesarean section which may be used in emergency situations and may also be given prophylactically in cases such as breech presentation and in delivery of the preterm infant where fetal trauma is possible. The use of a metered-dose sublingual spray is ideally suited to obstetric practice, being both easy to use and also rapidly administered.

Psychiatric findings among child psychiatric inpatients grouped by public and private payment.

OBJECTIVE: The study compared school-age psychiatric inpatients whose care was publicly funded with those whose care was privately funded to determine whether the public patients presented with more psychiatric risk factors and more psychiatric problems. METHODS: Retrospective chart review was used to collect data on the demographic and personal characteristics, behavior in the hospital, and response to milieu treatment of 40 public patients and 40 private patients. Half of each group were admitted during 1985-1986, and half during 1991-1993. Characteristics of the two groups were compared, and trends over time were examined. RESULTS: The public group presented for hospitalization with significantly more risk factors and psychiatric problems. Public status predicted the use of certain interventions, such as time-outs and physical holding. Public patients responded less positively to the treatment program. They had three times the number of bed-days as the private group during 1991-1993. CONCLUSIONS: Public patients require more intensive and extensive inpatient treatment and will be more profoundly affected by the restrictions on psychiatric inpatient care in the current climate of fiscal restraint.
