Venous air embolism in posterior fossa surgery is a well-documented complication. Various highly sensitive devices help in early detection of air embolism. In management of air embolism, sealing the site of air entry is an important step in preventing further episodes. Here we discuss the importance of inspiratory hold after lung inflation (Valsalva maneuver) in helping to localize the site of air entry and its role in the management of venous air embolism observed in two cases of posterior fossa mass, operated in sitting position.
后颅窝手术中的静脉空气栓塞是一种有充分文献记载的并发症。各种高灵敏度设备有助于早期检测空气栓塞。在空气栓塞的处理中，封闭空气进入部位是预防进一步发作的重要步骤。在此，我们讨论在肺充气后屏气（瓦尔萨尔瓦动作）在帮助定位空气进入部位方面的重要性及其在两例后颅窝肿块患者坐位手术中观察到的静脉空气栓塞处理中的作用。
