Background There is controversy about whether capnography is adequate to monitor pulmonary ventilation to reduce the risk of significant respiratory acidosis in pregnant patients undergoing laparoscopic surgery. In this prospective study, changes in arterial to end-tidal carbon dioxide pressure difference (PaCO2--PetCO2), induced by carbon dioxide pneumoperitoneum, were determined in pregnant patients undergoing laparoscopic cholecystectomy. Methods Eight pregnant women underwent general anesthesia at 17-30 weeks of gestation. Carbon dioxide pnueumoperitoneum was initiated after obtaining arterial blood for gas analysis. Pulmonary ventilation was adjusted to maintain PetCO2 around 32 mmHg during the procedure. Arterial blood gas analysis was performed during insufflation, after the termination of insufflation, after extubation, and in the postoperative period. Results The mean +/- SD for PaCO2--PetCO2 was 2.4 +/- 1.5 before carbon dioxide pneumoperitoneum, 2.6 +/- 1.2 during, and 1.9 +/- 1.4 mmHg after termination of pneumoperitoneum. PaCO2 and pH during pneumoperitoneum were 35 +/- 1.7 mmHg and 7.41 +/- 0.02, respectively. There were no significant differences in either mean PaCO2--PetCO2 or PaCO2 and pH during various phases of laparoscopy. Conclusions Capnography is adequate to guide ventilation during laparoscopic surgery in pregnant patients. Respiratory acidosis did not occur when PetCO2 was maintained at 32 mmHg during carbon dioxide pneumoperitoneum.

Background: In order to perform laparoscopic procedures, it is necessary to first access the peritoneal cavity and establish carbon dioxide pneumoperitoneum. The placement of the first trocar remains a critical step in laparoscopic surgery. In order to minimize complications associated with placement of first trocar, several techniques have been reported. Author describe a surgical technique that provides a quick, safe, and reliable initial access to the peritoneal cavity with its excellent functional and cosmetic results.Methods: Retrospective study of patients who underwent various laparoscopic procedures at Maxx lyfe Hospital, Bathindi, Jammu was carried out by the closed technique for initial access to the peritoneal cavity through the umbilicus from July 2016 to May 2019. In this study, patients who had a prior midline laparotomy with involvement of the umbilicus were excluded.Results: Authors analyzed 456 patients (M = 190; F = 266) in the study period. Average age of the patients was 32 years (range:12-86). A physiologic defect was identified in the umbilical region in all patients who had no history of previous abdominal surgery in that region. The average time to access the peritoneal cavity was 30 seconds (range: 20-50).Conclusions: This technique is quick, safe, reliable, simple, and easy to learn and easy to perform. It is associated with no mortality and minimal morbidity and has excellent cosmetic results. Based on authors experience, authors believe that this method provides surgeons with an effective and safe way to insert the first trocar and recommend it as a routine procedure to access the peritoneal cavity for abdominal laparoscopic surgery.

Laparoscopic surgery results in physiologic changes that encompass multiple organ systems, with respiratory, cardiovascular and neurologic and splanchnic effects. Insufflation of the peritoneum results in reduced lung volumes, atelectasis, and endobronchial migration of the endotracheal tube. Pneumoperitoneum can result in changes to venous return, cardiac output and blood pressure. Hypercapnia due to carbon dioxide gas used in insufflation can reduce cerebral perfusion pressure. Complications during laparoscopic surgery often occur during port placement and creation of the pneumoperitoneum. Problems include injury to blood vessels during trocar entry, vascular injury in the pneumoperitoneum with limited surgical access, severe bradycardia and arrhythmias due to vagal stimulation from peritoneal stretching, subcutaneous emphysema, pneumothorax, gas embolism, and complications associated with steep Trendelenburg positioning. A thorough understanding of the physiologic changes associated with laparoscopic procedures and recognition of potential complications will facilitate in optimal patient care.  This review contains 4 figures, 1 table and 52 references Keywords: Laparoscopy; laparoscopic surgery; carbon dioxide; pneumoperitoneum; capnothorax; general anesthesia; subcutaneous emphysema; insufflation
