Randomized Controlled Trial Comparative Study Clinical Trial
Oxytocin injection after caesarean delivery: intravenous or intramyometrial?
To determine, after Caesarean delivery, uterine contractility and blood pressure following intravenous (i.v.) and intramyometrial (imy) injection of oxytocin. ⋯ Intramyometrial administration of 20 IU oxytocin after Caesarean delivery is associated with more severe hypotension than is i.v. injection of 5 IU oxytocin. Route of oxytocin injection did not affect uterine tone.

Calcium channel blockers attenuate cardiovascular responses to tracheal extubation in hypertensive patients.
Hypertensive patients exhibit exaggerated cardiovascular responses to tracheal extubation. This study was undertaken to examine the inhibitory effects of calcium channel blockers, nicardipine and diltiazem, on haemodynamic changes after tracheal extubation. ⋯ Compared with nicardipine, administration of diltiazem produced greater attenuating the circulatory responses to tracheal extubation in hypertensive patients.

Randomized Controlled Trial Clinical Trial
Intrathecal sufentanil as the sole agent in combined spinal-epidural analgesia for the ambulatory parturient.
To compare the effect of a combination of intrathecal (i.t.) sufentanil plus bupivacaine with i.t. sufentanil alone, on the incidence of hypotension and the success of ambulation in parturients. ⋯ The quality of analgesia in all subjects in the study was excellent. Side effects were more common in the i.t. sufentanil-bupivacaine combination group.

Smoking increases the requirement for rocuronium.
To compare the potency of rocuronium in non-smokers and smokers during general anaesthesia. ⋯ The results may indicate increased metabolism of rocuronium in smokers rather than increased requirement of rocuronium at the receptor site.

Supplementation of general anaesthesia with tramadol or fentanyl in parturients undergoing elective caesarean section.
Tramadol has been recommended for analgesia in parturients undergoing vaginal delivery. The present report investigated the effect of tramadol versus fentanyl on umbilical vein (UV) blood gases and Apgar scores of neonates delivered via elective Caesarean section under general anaesthesia. ⋯ Tramadol is associated with a high incidence of intraoperative maternal recall and can result in lower umbilical vein PO2 and higher PCO2 than in the fentanyl group.
