Role of EtCO2 (End tidal CO2) Monitoring (Capnography) During Laparoscopic Surgery under General Anesthesia
Journal Title: International Journal Of Research In Medicine - Year 2016, Vol 5, Issue 4
Abstract
BACKGROUND: The rapid development of laparoscopic surgeries demands concurrent advancement in Anesthesthetic techniques and monitoring standards.The laparoscopic surgery requires creation of pneumoperitonium which has detrimental effects on Cardiovascular and Respiratory system. So, vigilant monitoring of ECG,SPO2,NIBP and EtCO2 is mandatory. We studied efficacy and advantages of EtCO2 monitoring in laparoscopic surgery . METHODS & MATERIALS: Total 60 patients belonging to ASAPS-I, II, III posted for various Laparoscopic surgeries were enrolled for the study. Conventional General Anesthesia was administered in all the patients. Monitoring was done in the form of Temperature, Pulse rate, ECG, NIBP, SPO2 and ETCO2 at a regular interval. Variables like Type of surgery, Duration of carboperitonium, Approach, No. of surgical ports, IAP and flow rate of CO2 insufflation were noted down. Increase in EtCO2 level and any complications related to carboperitonium, CO2 insufflation and laparoscopy were also noted. RESULTS: We found that increase in EtCO2 (Hypercarbia) was observed in old age patients, longer duration of pneumoperitonium, extraperitoneal approach and IAP > 16 mm of Hg. The rise in the EtCO2 level was mainly observed 20min after pneumoperitonium. 40% of patients developed hypertension and tachycardia. In 10 cases, subcutaneous emphysema was observed. None of our patient developed fall in SpO2, Pneumothorax or Air embolism. CONCLUSION: The EtCO2 immediately reflects changes in circulatory status and ventilation as well as detects complications during Laparoscopic surgery.
