ObjectiveTo investigate the effect of pressure control ventilation-volume guaranteed (PCV-VG) for patients undergoing da Vinci robotic-assisted pulmonary lobotomy. MethodA total of 40 patients undergoing Da Vinci robotic-assisted pulmonary lobotomy were randomly divided into two groups:a PCV-VG group (G group) and a volume-controlled ventilation (VCV) group (V group). There were 20 patients in each group with 13 males and 7 females at age of 49.0±5.5 years in the G group, 16 males and 4 females at age of 51.0±3.9 years in the V group. Haemodynamics indexes and oxygenation parameters were recorded at different times and compared between the two groups. ResultsDuring one-lung ventilation (OLV) period, the peak inspiratory pressure (Ppeak), respiratory index (RI) and arterial partial pressure of carbon dioxide (PaCO2) in the G group were statistically lower than those in the V group (P<0.05). While the Cdyn and inspired oxygen fraction(OI) were higher in the G group than those in the V group (P<0.05). ConclusionCompared with the traditional VCV ventilation mode, the PCV-VG ventilation mode improves Ppeak, Cdyn, OI, and RI of the patients undergoing da Vinci robotic-assisted pulmonary lobotomy.
ObjectiveTo summarize the management of anesthesia during robotic off-pump coronary artery bypass grafting (CABG) with the da Vinci surgical system in minimal thoractomy. MethodsFrom May 2011 to December 2014, 24 patients (20 males and 4 females) at the average age of 62.1±12.8 years underwent robotic off-pump CABG with the da Vinci surgical system in our hospital. All the patients underwent the continuous invasive blood pressure monitoring, endotracheal intubation with the double-lumen tube after induction of general anesthesia, fiber bronchoscope positioning, intraoperative application of one-lung ventilation, placing the Swan-Ganz floating catheter, and monitoring the echocar-diography (TEE) and blood gas analysis and indexes of hemodynamics. ResultsAll the patients were stable during the anesthesia induction period. There was no severe hypoxemia and hypercapnia. The surgery was successful and there was no thoracotomy. All the patients left off breathing machine postoperatively.The duration of mechanical ventilation was 5.3±2.8 hours. All patients were moved out from ICU in 18 hours.There was no thoracotomy for hemostasis after surgery. All the patients were discharged on the fourth or fifth day postoperatively. There was no death relevant to surgery or perioperative complications. There was no recurrence of cardiovascular events on the 30th day,3 months and 6 months postoperative follow-up. ConclusionThis anesthesia method is safe and effective. It is a rapid recovery way with the fewer complications, less suffering of the patients, reliable anesthesia management and high satisfaction of the patients'.
