METHODS: Subjects were 200 consecutive patients admitted to Kuala Tereng-ganu General Hospital, Malaysia with severe hypertension in pregnancy between August 1989 and June 1990. Admission criteria were an ongoing viable pregnancy more than 28 weeks and diastolic blood pressure (DBP) more than 120 mmHg. The patients were randomly divided into 2 groups. In group I, sublingual nifedipine 5 mg was administered and repeated after 15 minutes if DBP > 120 mmHg; and in group II hydrallazine 5 mg was intravenously injected and repeated after 15 minutes if DBP > 120 mmHg. Both groups were put on hydrallazine infusion if DBP > 120 mmHg after 30 minutes. The Chi-square test was used for analysis with significance at p < 0.05.

RESULTS: There was no statistical difference in the efficacy of therapy for decreasing blood pressure between the 2 groups. The groups were comparable by age, parity, gestational age at presentation, birth weight of infants, incidence of postpartum haemorrhage and fetal distress. Caesarian section rates were similar. In the observational studies on nurses administering the drugs, no significant difficulties were observed.

METHODS: Seventy-five patients were given propofol for induction of anaesthesia. Twenty-five patients received a single bolus, 25 patients received an infusion, and 25 patients received a bolus followed by an infusion. Computer simulation was used to derive the central compartment concentration. The keo that brought about the same value for Ce at loss of the eyelash reflex using the three methods of injection was derived.

RESULTS: Keo was found to be 0.80 min(-1). Mean (SD) Ce at loss of the eyelash reflex was 2.27 (0.69) microg ml(-1).

DATA SOURCES: MEDLINE, EMBASE, PubMed, and the Cochrane Database of Systematic reviews were searched from their inception until June 2017.

REVIEW METHODS: All randomized controlled trials, observational studies, and case-control studies were included. Case reports, case series, nonsystematic reviews, and studies that involved children were excluded.

RESULTS: Nine studies (n = 464) were eligible in the data synthesis. Both continuous and bolus furosemide resulted in no difference in all-cause mortality (7 studies; n = 396; I2 = 0%; fixed-effect model [FEM]: odds ratio [OR] 1.15 [95% confidence interval (CI) 0.67-1.96]; p = 0.64). Continuous furosemide was associated with significant greater total urine output (n = 132; I2 = 70%; random-effect model: OR 811.19 [95% CI 99.84-1,522.53]; p = 0.03), but longer length of hospital stay (n = 290; I2 = 40%; FEM: OR 2.84 [95% CI 1.74-3.94]; p < 0.01) in comparison to the bolus group. No statistical significance was found in the changes of creatinine and estimated glomerular filtration rate between both groups.

METHODS: : Nulliparas with uncomplicated PROM at term, a Bishop score less than or equal to 6, and who required labor induction were recruited for a double-blind randomized trial. Participants were randomly assigned to 3-mg dinoprostone pessary and oxytocin infusion or placebo and oxytocin infusion. A cardiotocogram was performed before induction and maintained to delivery. Dinoprostone pessary or placebo was placed in the posterior vaginal fornix. Oxytocin intravenous infusion was commenced at 2 milliunits/min and doubled every 30 minutes to a maximum of 32 milliunits/min. Oxytocin infusion rate was titrated to achieve four contractions every 10 minutes. Primary outcomes were vaginal delivery within 12 hours and maternal satisfaction with the birth process using a visual analog scale (VAS) from 0 to 10 (higher score, greater satisfaction).

RESULTS: : One hundred fourteen women were available for analysis. Vaginal delivery rates within 12 hours were 25 of 57 (43.9%) for concurrent treatment compared with 27/57 (47.4%) (relative risk 0.9, 95% confidence interval 0.6-1.4, P=.85) for oxytocin only; median VAS was 8 (interquartile range [IQR] 2) compared with 8 (IQR 2), P=.38. Uterine hyperstimulation was 14% compared with 5.3%, P=.20; overall vaginal delivery rates were 59.6% compared with 64.9%, P=.70; and induction to vaginal delivery interval 9.7 hours compared with 9.4 hours P=.75 for concurrent treatment compared with oxytocin, respectively. There was no significant difference for any other outcome.

CONCLUSION: : Concurrent vaginal dinoprostone and intravenous oxytocin for labor induction of term PROM did not expedite delivery or improve patient satisfaction.

DESIGN: Serum intact parathormone (PTH) concentrations were measured on samples taken before and during a variable-rate tri-sodium citrate infusion designed to 'clamp' the whole blood ionised calcium concentration 0.20 mmol L-1 below baseline for 120 min.

SUBJECTS: Six Malaysian patients aged 17-42 years with acute malaria, four of whom were restudied in convalescence, and 12 healthy controls aged 19-36 years.

MAIN OUTCOME MEASURES: Whole-blood ionised calcium and serum intact PTH concentrations.

RESULTS: The mean (SD baseline ionised calcium was lower in the malaria patients than in controls (1.09 +/- 0.06 vs. 1.18 +/- 0.03 mmol L-1, respectively; P = 0.01) but PTH concentrations were similar (3.0 +/- 1.8 vs. 3.3 +/- 1.3 pmol L(-1); P = 0.33). Target whole-blood ionised calcium concentrations were achieved more rapidly in the controls than the patients (within 15 vs. 30 min) despite significantly more citrate being required in the patients (area under the citrate infusion-time curve 0.95 (0.25 vs. 0.57 +/- 0.09 mmol kg-1; P < 0.01). The ratio of the change in serum PTH to that in ionised calcium (delta PTH/ delta Ca2+), calculated to adjust for differences in initial rate of fall of ionised calcium, was similar during the first 5 min of the clamp (132 +/- 75 x 10(-6) vs. 131 +/- 43 x 10(-6) in patients and controls, respectively, P > 0.05), as were steady-state serum PTH levels during the second hour (7.0 +/- 2.2 pmol L-1 in each case). Convalescent patients had normal basal ionised calcium levels but the lowest serum intact PTH levels before and during the clamp, consistent with an increase in skeletal PTH sensitivity after treatment.
