Review Comparative Study
Carbon dioxide absorption during laparoscopic pelvic operation.
Several factors may influence the degree of carbon dioxide (CO2) absorption during laparoscopy. Hypercapnia as a result of excessive CO2 absorption may have adverse clinical effects. ⋯ The risk factors for hypercapnia can be identified. Careful consideration of the patient's ability to tolerate hypercapnia should be made when planning extraperitoneal laparoscopy, especially if the procedure is likely to be prolonged. The clinical development of subcutaneous emphysema should alert the surgeon to the possibility of subsequent hypercapnia.

Electrosurgical injuries occur during laparoscopic operations and are potentially serious. The overall incidence of recognized injuries is between one and two patients per 1,000 operations. The majority go unrecognized at the time of the electrical insult and commonly present three to seven days afterward with fever and pain in the abdomen. Since these injuries appear late the pathophysiology remains speculative. ⋯ An awareness of the hazards of diathermy together with an understanding of the mechanisms of injury should enable the surgeon to dissect tissue and to achieve hemostasis, while at the same time decreasing the risk of serious complications to the patient.
