Increased ventilation requirements during obstetric general anaesthesia.
The inspiratory fresh gas flow rate (FGF) required to produce an end-tidal carbon dioxide tension (PE'CO2) of 4 kPa during general anaesthesia, neuromuscular blockade and artificial ventilation, was compared in a group of 46 obstetric patients and a matched group of 50 non-pregnant female patients. The non-pregnant patients required a mean (SD) inspiratory FGF of 77 (10.6) ml kg-1 min-1, wherea...
متن کاملA ventilation strategy during general anaesthesia to reduce postoperative atelectasis
BACKGROUND Atelectasis is common during and after general anaesthesia. We hypothesized that a ventilation strategy, without recruitment manoeuvres, using a combination of continuous positive airway pressure (CPAP) or positive end-expiratory pressure (PEEP) and a reduced end-expiratory oxygen fraction (FETO2) before ending mask ventilation with CPAP after extubation would reduce the area of post...

was not indicated in this case; this was confirmed after discussion with our neurosurgical colleagues. Although pulsatile bleeding is usually associated with arterial puncture, in the clinical situation of pregnancy and labour in particular, raised intra-abdominal pressure can cause increased venous pressure within the valveless venous plexus of Bateson potentially producing significant haemorr...
