Lung Function In Patients With Damage To Laparoscopic Surgery Tolerability Of Research

Objective By observation of lung function changes in patients with varying degrees of impairment of lung function in general anesthesia for laparoscopic surgical procedures, explore the impairment of lung function in the preoperative grading and assessment in such surgeryMethods Choose elective laparoscopic abdominal surgery,65patients, ASA I-III,levelaccording to the degree of impairment of lung function in the preoperative grading points A, B, C, D, four groups, each intraoperative mechanical ventilation.10min (T1) to monitor the pneumoperitoneum, the gas injection after60min (T2),120min (T3), and180min (T4), MAP, HR, A-aDO2of PETCO2and arterial blood gas analysis, electrocardiogram, and so on.Results Four groups of patients compared to age, weight, operative time were not statistically significant, compared with before pneumoperitoneum, D, MAP were increased, group D of HR increased. Compared with group A, group D of the gas belly MAP and HR were higher than group A, and four cases of frequent premature ventricular contractions, five cases of blood pressure fluctuations,the change of4patients PH, PaO2, PaCO2:before pneumoperitoneum compared four groups of patients after gas injection PaCO2were significantly higher, four groups of patients after the gas injection C,D, were the PaO2and pH decreased. Compared with group A, preoperative C and Group D, PaO2decreased, Group D PaCO2increased; after gas injection, Group D PaCO2increased, PaO2and pH decreasedFour peak airway pressure values (Ppeak), respiratory compliance (Compl), end-tidal carbon dioxide value before the change of minute ventilation (VE):pneumoperitoneum, gas belly of a four-group, VE were significantly higher the Compl were decreases. Compared with group A, group D and Ppeak, the VE of each period were significantly higher, Group C after the gas injection60min,120min,180min increased; group D Compl each period decreases in group C after the gas injection60min120min180min both decreasedFour groups of oxygenation in patients with indicators of change: before pneumoperitoneum, gas injection, C and D, two groups of OI lower, Pa-etCO2increased o four groups of patients at each time point after the gas injection A-aDO2increased. With group A, the pneumoperitoneum Group DOI lower, gas injection, C and D of OI decreased. Pneumoperitoneum group C Pa-etCO2higher. Group D A-aDO2, Pa.-etCO2increased after gas injection, both groups A-aDO2increased Pa-etCO2increased Conclusions Patients undergoing laparoscopic surgery with preoperative impairment of lung function impairment of lung function should be carried out before the grading and assessment; patients with mild impairment of lung function can tolerate the180min less CO2pneumoperitoneum;Patients with moderate impairment of lung function in180minCO2pneumoperitoneum exist CO2accumulation, mild respiratory acidosis, and oxygenation index decreased; severe impairment of lung function in patients with180min of CO2pneumoperitoneum exists not only the accumulation of CO2, respiratory acidosis, and oxygenation obstacles circulation changes, long pneumoperitoneum surgery must be taken seriously.
