Comparative StudyThoracoscopic microsurgical technique for vertebral surgery--anesthetic considerations.
The thoracoscopic microsurgical technique (TMT) for vertebral and spinal cord surgery is associated with the benefits of reduced postoperative pain, accelerated return to physical activity and reduced complication rates. However, because of the surgeon's requirement of a non-ventilated lung, it confronts the anesthesiologist with the need for extremely long duration of single-lung ventilation (SLV). ⋯ We conclude that despite the long duration of SLV, TMT is a reasonable alternative to open thoracotomy for thoracic neurosurgical spine procedures because of the substantial clinical benefits of accelerated return to physical activity, reduced complication rates and reduced intensive care unit and hospital stay.

Forward blood flow during cardiopulmonary resuscitation in patients with severe accidental hypothermia. An echocardiographic study.
The mechanism responsible for the forward blood flow associated with external chest compression is still controversial. Evidence for both blood flow caused by direct cardiac compression and blood flow generated by a general increase in intrathoracic pressure has been found in experimental as well as clinical studies. No data are available concerning the mechanism causing forward blood flow in hypothermic patients undergoing cardiopulmonary resuscitation. Therefore, echocardiographic findings during external chest compression in seven hypothermic arrest victims are reported. ⋯ In contrast to normothermic arrest victims, an open mitral valve during external chest compression is a common finding during hypothermia, indicating that thoracic pump mechanism is important for forward blood flow during cardiopulmonary resuscitation in hypothermic arrest victims. Aortic valve opening in two hypothermic arrest victims suggests forward blood flow also during active decompression of the thorax with the Cardiopump.

1 MAC-incision sevoflurane prevents explicit awareness during surgical skin incision and tracheal intubation.
This study tested the hypothesis that 1 MAC-incision anesthesia secures unconsciousness during surgical skin incision and tracheal intubation. ⋯ It is concluded that 1MAC-incision sevoflurane secures unconsciousness during surgical skin incision and tracheal intubation.
