Summary: | Purpose/Aim of the study: We investigated the effects of different positive end-expiratory pressure (PEEP) levels on postoperative respiration parameters in patients undergoing laparoscopic cholecystectomy. Materials and Methods: One hundred and five consecutive patients were randomly divided to three groups (n = 35, for each group). Group I did not receive PEEP whereas group II received PEEP as 5 cmH2O and group III received PEEP as 8 cm H2O. Measurements with spirometer were taken 1 hour before the operation (T1) and, 1 (T2), 6 (T3), and 24 hours (T4) after extubation by an anesthetist. Forced expiratory volume (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF) were recorded. Results: Group I had higher FVC values measured at T2 time point compared with other groups (p < 0.05, for both groups). There was a statistically significant difference between group I and group III in terms of the FVC values measured at T3 and T4 time points (p = 0.05 and p < 0.05, retrospectively). A statistical difference was found between group I and group II in terms of FEV1 measured at T2 time point (p < 0.05). Group I had higher FEV1 values measured at T3 and T4 time points compared to group III (p = 0.05, P<0.05; respectively). Group III had lower PEF values measured at T4 time point compared to group I and II (p < 0.05). Conclusions: We concluded that PEEP with 5 or 8 cmH2O has negative effects on lung function tests measured with spirometer during postoperative 1st, 6th, and 24th hours in patients underwent elective laparoscopic cholecystectomy. |
