Comparative aspects of respiratory support via laringeal air ducts and endotracheal tube for video-assisted onkothoracic operations

Abstract

To improve patient 's recovery after video-assisted thoracoscopic lobectomies (VATSL) by laryngeal mask using. This is a comparative analysis of 74 patients underwent VATSL. In 37 patients anaesthesia consisted of sevoflurane and fentanyl, myorelaxant, respiratory support via independent ventilation of either lung. In another 37patient 's anaesthesia protocol included respiratory support performed via laryngeal mask, propofol infusion and epidural analgesia with ropivacaine 0,2% and fentanyl. During the operation in both groups we evaluated hemodynamic, arterial blood gases, leukocytes, glucose and cortisol blood level, time to consciousness restoration (Aldrete-score) and time to discharge from ICU and duration of hospital stay, frequency of complications. Patients with ventilation through laryngeal mask showed a statistically lower stress-reaction, avoided bronchoscopy with BAL and frequency of complications. Duration of inhospital stay in patients with laryngeal mask was 7±1,3 days; in intubated patients was 11±3,2 days. In case of ventilation through the laryngeal mask hyper dynamic state of circulation, glycemia, leukocytes, cortisol blood level and arterial blood pH were lower, whereas Pa CO₂ increase. The number of bronchoscopy with BAL and time to discharge from ICU and from hospital not having risk of postoperative complications --lower.
