Laparoscopic surgery is replacing conventional surgical techniques due to its many advantages. However the possibility of respiratory complications during CO2-induced pneumoperitoneum remain. Tracheal gas insufflation (TGI) has been shown to be a useful adjunct to mechanical ventilation in hypercapneic patients. This study investigated the effectiveness of TGI in reducing the PaCO2 level in hypercapneic patients during laparoscopic surgery without increasing the peak inspiratory pressure (PIP) and usefulness of a Univent tube(R) as a device for TGI.
Twenty-four patients who were scheduled to undergo gynecological laparoscopic surgery, were enrolled in this study. Anesthesia was induced and maintained with propofol, rocuronium and N2O-O2-sevoflurane. The suction port of the endobronchial blocker of the Univent tube(R) was used for the path of TGI. Data including the ABGA and respiratory parameters were measured three times, the pre-CO2 peritoneum (pre-CO2 pneumoperitoneum point, PCP), 15 min after CO2 peritoneum (after-CO2 pneumoperitoneum point, ACP) and after 15 min TGI (TGI point, TGIP).
At ACP, the PaCO2 and PIP had increased more significantly than PCP. After TGI, the PaCO2 was decreased more significantly than ACP, but the PIP did not increased.
TGI is a useful adjunct to mechanical ventilation in hypercapneic patients during laparoscopic surgery, and a univent tube(R) is an economic and convenient device for TGI.
