Aim. Video-assisted thoracoscopy surgery (VATS) is classically performed using general anesthesia with a double-lumen endotracheal tube to allow collapse of the operated lung. However, according to our opinion, the risks of general anesthesia with one-lung ventilation could be accepted when major thoracic operation is planned, but it should be avoided or kept at minimum when performing less invasive procedures such as video-assisted talc pleurodesis. In this paper, 2 different protocols are described in order to demonstrate the effectiveness and safety of Monitored Anesthesia Care (MAC) for performing VATS talc pleurodesis.
Methods. We studied 65 neoplastic patients ASA III-IV who underwent video-assisted pleurodesis with talc nebulization. They were randomized into 2 homogenous groups: Group 1, received midazolam (0.015-0.030 mg/kg) and sufentanil (0.15-0.20 µg/kg); Group 2, received midazolam (0.15-0.2 mg/kg) and continuous remifentanil infusion 0.5-1 µg/kg/min in the first minute, followed by 0.05 µg/kg/min. Local anesthesia with 0.2% ropivacaine was emplo-yed before the thoracoscopic trocar was inserted in both groups. Intraoperative standard monitoring required ECG, heart rate, non-invasive blood pressure, transcutaneous carbon dioxide and oxygen saturation. Consciousness status has been evaluated by Ramsey scale, while pain intensity by VAS scale.
Results. No statistically significant fluctuations were observed for mean arterial pressure, heart rate, SpO2, tCO2, VAS and Ramsey score. No postoperative complications and hospital mortality occurred.
Conclusion. Both the protocols offer an efficient control of analgosedation with a minimum incidence of intraoperative and postoperative side effects. Anyway, the titration of the drug, is very important.
