Treatment of post-spinal hypotension during caesarean section assumes special concern in pre-eclamptic patients due to a compromised fetoplacental circulation and increased risk of placental hypoperfusion. Phenylephrine and ephedrine are the most commonly used vasopressors, although the best choice is still not clear. We studied 80 pre-eclamptic women with a singleton pregnancy who underwent caesarean section with spinal anaesthesia, and who developed hypotension defined as a decrease in systolic arterial pressure ≥ 20% from baseline or absolute value < 100 mmHg. Women were randomly allocated to receive phenylephrine 50 μg or ephedrine 4 mg boluses for treatment of hypotension. Blood pressure changes following vasopressor administration were similar in both groups, but heart rate remained higher after ephedrine at all time-points. The primary outcome measure of umbilical artery pH was 7.26 (0.11) in the phenylephrine group and 7.25 (0.09) in the ephedrine group (p = 0.86). The incidence of neonatal acidosis (umbilical artery pH < 7.20) was 9 (22.5%) in the phenylephrine group and 11 (27.5%) in the ephedrine group (p = 0.80). Other secondary outcome measures were comparable. In conclusion, phenylephrine 50 μg and ephedrine 4 mg, administered as intravenous boluses to treat post-spinal hypotension during caesarean section in pre-eclamptic patients, resulted in similar fetal acid-base values, were equally effective in treating hypotension and were associated with good maternal and neonatal outcome.
Introduction:The prediction of mortality in acute pancreatitis (AP) is a useful estimate for effective treatment. Scoring systems such as acute physiology and chronic health evaluation (APACHE) II, computed tomography (CT) severity index (CTSI), bedside index of severity in acute pancreatitis (BISAP), etc., are used for prediction. Biomarkers like C-reactive protein (CRP) and procalcitonin (PCT) are also considered useful for prognostication. The aim of this retrospective study was to correlate the changes in serum PCT level with APACHE II score between admission and 48 hours as mortality predictor in AP. Materials and methods: The observational study was conducted in a cohort of 42 patients admitted consecutively in the seven-bedded general intensive care unit (ICU) of our institute between June 2016 and May 2018, with the diagnosis of AP. The APACHE II score and serum PCT level at admission and 48 hours were retrieved from the hospital database. The change in APACHE II and PCT level was compared between ICU "survivors" and "nonsurvivors. " The predictive accuracy of APACHE II and PCT was measured using area under receiver-operator characteristics (ROC) curve. A p value <0.05 was considered as significant. Results: Of the 42 patients enrolled, 30 patients (71.42%) were survivors and 12 (28.58%) were nonsurvivors. The median APACHE II score in nonsurvivors increased from 16 (7-19) to 23 (11-29) and remained unchanged at 16 (9-19 at admission; 10-22 at 48 hours) in survivors. The median PCT levels increased from 3.8 (1.2-5.6) to 6.2 (1.9-12.5) in nonsurvivors and decreased from 3.8 (1.2-5.6) to 2.2 (0.6-2.9) in survivors. Serum PCT change compared better than the APACHE II score change among survivors (r = 0.455, p = 0.011) with a mean (±standard deviation SD) change of 1.41 (±1.59).
Conclusion:The change in serum PCT and APACHE II between admission and 48 hours correlates well and is useful for mortality prediction in AP. Serum PCT change compares better than APACHE II score change in survivors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
