Effect of serum 25-hydroxy vitamin D (25[OH] D) levels on the recovery of critically ill mechanically ventilated patients is unclear. Hence, this study assessed 25(OH)D levels of critically ill patients on mechanical ventilation at the time of admission to the Intensive Care Unit (ICU) and its relationship with clinical outcome. ⋯ Low Vitamin D level at admission did not affect 30-day mortality of critically ill patients on mechanical ventilation.

Although spinal anaesthesia (SA) is nowadays the preferred anaesthesia technique for caesarean section (CS), it is associated with considerable haemodynamic effects, such as maternal hypotension. This study aimed to evaluate a wide range of variables (related to parturient and anaesthesia techniques) associated with the incidence of different degrees of SA-induced hypotension during elective CS. ⋯ Age, body mass index, weight gain, gravidity, history of hypotension, baseline SBP and heart rate, fluid preloading, adding sufentanil to bupivacaine and sensory block hieght were the main risk factors identified in the study for SA-induced hypotension during CS.

Hypotension during propofol induction is a common problem. Perfusion index (PI), an indicator of systemic vascular resistance, is said to be predictive of hypotension following subarachnoid block. We hypothesised that PI can predict hypotension following propofol induction and a cut-off value beyond which hypotension is more common can be determined. ⋯ Perfusion index could predict hypotension following propofol induction, especially before endotracheal intubation, and had a very high negative predictive value.

The external jugular vein (EJV), often used for resuscitation, has been underutilised for central venous catheterisation (CVC) in view of an unpredictable success rate. There is an encouraging literature on the improved success rate of CVC through EJV with the inclusion of certain body manoeuvres. This prospective randomised controlled study was conducted with the aim of evaluating the efficacy of body manoeuvres in improving the success rate of CVC through EJV. ⋯ Inclusion of various body manoeuvres to Seldinger technique significantly improves the success rate of CVC through EJV.

Apnoeic oxygenation during laryngoscopy has been emphasised in recent recommendations for airway management. We aimed to compare the effect of nasal oxygen supplementation on time for pulse oximeter oxygen saturation (SpO2) to fall from 100% to 92% (desaturation safety time), to assess the arterial oxygen partial pressures (PaO2) with and without nasal oxygen supplementation and the time for SpO2 to recover from 92% to 100% after initiation of ventilation. ⋯ Apnoeic oxygen supplementation at 10 L/min flow by nasal prong did not significantly prolong the apnoea desaturation safety periods or the PaO2 in our study.
