There is uncertainty as to whether addition of magnesium sulfate to spinal local anesthetics improves quality and duration of block in the caesarean section. In this randomized double blind clinical trial study, we investigated the effect of adding different doses of intrathecal magnesium sulfate to bupivacaine in the caesarean section. ⋯ In patients undergoing the caesarean section under hyperbaric bupivacaine spinal anesthesia, the addition of 50, 75, or 100 mg magnesium sulfate provides safe and effective anesthesia, but 75 mg of this drug was enough to lead a significant delay in the onset of both sensory and motor blockade, and prolonged the duration of sensory and motor blockade, without increasing major side effects.

The aim of this study was to compare the differences in the quality of analgesia by patient-controlled analgesia (PCA) and nurse-controlled analgesia (NCA) for post-caesarean section analgesia. ⋯ In post caesarean section, PCA morphine or methadone improves 24-h VAS compared with NCA.

The benefit of prophylactic combination therapy using crystalloid and colloid preload with ephedrine has not been cleared to prevent maternal hypotension after spinal anesthesia at cesarean delivery. This study evaluated the efficacy of three combinational methods to prevent hypotension following spinal anesthesia. ⋯ Combination of preventive methods decreased the occurrence of hypotension following spinal anesthesia to an acceptable level. Overall, the most effective method was a combination of crystalloid preload with ephedrine.

Eclampsia remains a problem in the developing countries despite improvements in antenatal care and emergency obstetric facilities. It is an important cause of maternal morbidity and mortality in Nigeria. A 26-year-old primipara, residing in an urban city in Nigeria with antenatal care facilities, booked for antenatal care at 36 weeks of gestation and was then diagnosed with severe pre-eclampsia. ⋯ Progression of pre-eclampsia to eclampsia during cesarean section under spinal anesthesia is rare, but it can occur. Early booking for antenatal care to enable an early diagnosis and treatment are necessary to prevent the progression of pre-eclampsia to eclampsia. There is need to educate the populace on the importance of ante natal care so as to improve its utilization.

There is insufficient evidence to conclude that the timing of tracheostomy alters the duration of mechanical ventilation, hence this study was designed to investigate the correlation between timing of tracheostomy and duration of mechanical ventilation for patients admitted to intensive care unit (ICU) with potentially normal lungs. ⋯ Our study with mentioned sample size could not show any relationship between timing of tracheostomy and duration of mechanical ventilation in patients under mechanical ventilation with good pulmonary function in ICU.
