Succinylcholine dosage and apnea-induced hemoglobin desaturation in patients.
BACKGROUND The authors examined the notion that a reduction in succinylcholine dose from 1 mg/kg to approximately 0.6 mg/kg would allow a faster recovery of spontaneous ventilation and reduction in the incidence of hemoglobin desaturation during the period of apnea in simulated complete upper airway obstruction situations. METHODS This prospective, randomized, double-blind study involved 60 p...
متن کاملCerebral oxygen desaturation during one-lung ventilation: correlation with hemodynamic variables.
PURPOSE Cerebral desaturation occurs frequently in patients undergoing one-lung ventilation for thoracic surgery. The mechanism of this desaturation is unclear regarding its etiology. The objective of this study was to investigate whether or not decreases in cerebral oxygen saturation associated with one-lung ventilation were a consequence of decreased cardiac output. METHODS A blinded observ...
متن کاملHemoglobin desaturation after succinylcholine-induced apnea: a study of the recovery of spontaneous ventilation in healthy volunteers.
BACKGROUND Because of the rapid recovery of neuromuscular function after succinylcholine administration, there is a belief that patients will start breathing sufficiently rapidly to prevent significant oxygen desaturation. The authors tested whether this belief was valid. METHODS Twelve healthy volunteers aged 18-45 yr participated in the study. After preoxygenation to an end-tidal oxygen con...
متن کاملHemoglobin desaturation after propofol/remifentanil-induced apnea: a study of the recovery of spontaneous ventilation in healthy volunteers.
BACKGROUND In an earlier study investigating the "can't ventilate/can't intubate" clinical scenario, induction of anesthesia with thiopental 5 mg/kg and succinylcholine 1.0 mg/kg was associated with a significant risk of hemoglobin desaturation. It appeared that succinylcholine-induced apnea was responsible for the prolonged apnea. Our hypothesis was that using propofol and remifentanil for tra...
متن کاملThe use of air in the inspired gas mixture during two-lung ventilation delays lung collapse during one-lung ventilation.
BACKGROUND Collapse of the ipsilateral lung facilitates surgical exposure during thoracic procedures. The use of different gas mixtures during two-lung ventilation (2LV) may improve or impede surgical conditions during subsequent one-lung ventilation (OLV) by increasing or delaying lung collapse. We investigated the effects of three different gas mixtures during 2LV on lung collapse and oxygena...
