Hypoxaemia is a common postoperative problem after thoracotomy. Oxygen therapy with continuous monitoring by pulse oximetry should be a routine practice. This study was conducted to compare the efficacy between nasal cannula and ventimask for post-thoracotomy oxygen supplementation on 20 patients divided into 2 groups of 10 each undergoing closed mitral commisurotomy. The study period was of 5 months duration from March to July, 1996. The mean oxygen saturation remained above 98% in both the groups receiving oxygen either by nasal cannula or ventimask. As there was adequate oxygenation, the cost benefit ratio favours the use of nasal cannula for routine postoperative oxygen supplementation in the closed mitral commisurotomy patients.
低氧血症是开胸术后常见的问题。采用脉搏血氧饱和度仪持续监测进行氧疗应成为常规做法。本研究旨在比较鼻导管和文丘里面罩对20例行闭式二尖瓣交界分离术的患者术后氧补充的疗效，将这20名患者分为两组，每组10人。研究期为1996年3月至7月，为期5个月。接受鼻导管或文丘里面罩吸氧的两组患者的平均血氧饱和度均保持在98%以上。由于有足够的氧合作用，成本效益比有利于在闭式二尖瓣交界分离术患者术后常规氧补充中使用鼻导管。
