“…Magnusson and Spahn concluded compression atelectasis occurred during general anesthesia and was caused by chest geometry and diaphragm position and motion [13]. Pneumoperitoneum also affected cephalic displacement of diaphragm and decreased functional residual capacity [14]. In agreement with previous studies, our study revealed that major laparoscopic pelvic surgery not only decreased lung volume due to cephalic displacement of the diaphragm, but also decreased diaphragmatic movement.…”

Major laparoscopic pelvic surgery requires steep Trendelenburg position with pneumoperitoneum for a long time. We investigated the effect of Trendelenburg position with pneumoperitoneum on diaphragmatic excursion and lung compliance during major laparoscopic pelvic surgery using M-mode sonography. Twenty patients undergoing elective pelviscopic radical hysterectomy were included in this study. Diaphragmatic excursion was measured at the following time points; after sedation, after intubation, 90 minutes after Trendelenburg position with pneumoperitoneum, and after operation with recovery of muscle relaxation. And lung compliance was measured using anesthetic machine under general anesthesia; after the intubation, 90 minutes after Trendelenburg position with pneumoperitoneum and after operation with recovery of muscle relaxation. In order to detect postoperative pulmonary complication, postoperative chest radiography was checked. Static lung compliance, dynamic lung compliance and diaphragmatic excursion were decreased during operation (P < 0.001, respectively). At the end of the operation with recovery of muscle relaxation, reduced diaphragmatic movement was not recovered as its excursion after sedation (P < 0.001). In conclusion, lung compliance was decreased following transiently decreased diaphragmatic excursion during major laparoscopic pelvic surgery.

“…In patients submitted to pneumoperitoneum, it is common to observe an increase in f (LEME et al, 2002) due to the reduction in pulmonary complacency and increase in PaCO 2 (NORMANDO et al, 2006;LEME et al, 2002). Andrade Junior (2009) reported that respiratory rate remained unchanged in cats subjected to induced pneumoperitoneum of 6 and 12 mmHg; contrary to the observed in this study, in which a reduction in f was observed in GTREN.…”

“…Studies in cats have reported the use intraabdominal pressure (IAP) of 6-12 mmHg (HONSHO et al, 2013;PINTO FILHO et al, 2014;CASE et a., 2015); the use of IAP of 10 mmHg was based in a previous study reported is sufficient for an abdominal procedure in cats (NORMANDO et al, 2006).…”

Effects of pneumoperitoneum and trendelenburg position on intraocular pressure (IOP) in isofluorane anesthetised cats

et al. 2019

The aim of this study was to determine whether a pneumoperitoneum of 10 mmHg combined or not with the Trendelenburg position could lead to significant changes in intraocular pressure (IOP), ocular pressure perfusion (OPP), and cardiorespiratory variables; as well as determine whether a correlation exists between IOP and mean arterial blood pressure (MAP), and/or partial pressure of carbon dioxide in arterial blood (PaCO2) in cats. Animals were allocated in two groups (n=7/group): GC (without inclination) and GTREN (Trendelenburg position). The variables were recorded before (baseline) and during 30 minutes (T5-T30) after insufflation. In GTREN, a reduction in heart rate was observed at T5 and in respiratory rate at T5 and T15. There was an increase in IOP at T5-T30 in comparison to baseline. There was a reduction in potential of hydrogen in arterial blood in both groups at all times in comparison to baseline. Partial pressure of carbon dioxide in arterial blood was increased at T15-T30 in GC and at T5-T30 in GTREN. In conclusion, the pneumoperitoneum of 10mmHg CO2 did not significantly affect IOP or OPP in cats anaesthetised with isofluorane and kept under spontaneous ventilation. However, induced pneumoperitoneum combined with Trendelenburg position resulted in an increase in IOP in cats subjected to the same anaesthetic conditions, but did not affect OPP.

“…Among all downsides, pulmonary complications stand out as risk factors of high morbidity in upper abdominal surgery 3 . Among the findings of revolutionary techniques, pneumoperitoneum, which is imperative for the laparoscopy, became the object of important studies owing to its high morbidity rate within the procedures 2 .…”

PURPOSE:To analyze the changes in both respiratory function and cardiopulmonary exercise tests results in patients subjected to laparoscopic cholecystectomy. METHODS:Fifty patients were evaluated (76% women) and the average age was 47.8±14.2 years. All individuals underwent the measurement of spirometry, manovacuometry, 6-minute walk test (6MWT) and stair-climbing test (SCT). All tests were performed at the first (PO1), fifth (PO5) and thirtieth (PO30) postoperative days. RESULTS:BMI average was 28.8±4.8 kg/m 2 . Sample comprised 68% non-smokers, 20% current smokers, and 12% former smokers.There was no incidence of postoperative complication whatsoever. There was a significant decrease in spirometric values at PO1, but values were similar to the ones of PRE at PO30. Manovacuometry showed alterations at PO1 displaying values that were similar to the ones of PRE at PO30. 6MWT was significantly shorter at until PO5, but at PO30 values were similar to ones of PRE. As for SCT, values were significantly compromised at PO5 and PO30 since they were similar to the ones of PRE. CONCLUSION:Patients submitted to laparoscopic cholecystectomy present a decrease in cardiorespiratory function on the first postoperative moments but there is a rapid return to preoperative conditions.
