TY - JOUR T1 - COMPARISON OF END-TIDAL CO2 LEVELS BEFORE AND AFTER BLOWING GAS IN THE ABDOMINAL CAVITY IN PATIENTS OF THE GYNECOLOGICAL SURGERY DEPARTMENT UNDERGOING LAPAROSCOPY TT - مقایسه میزان CO2 انتهای بازدمی قبل و بعد از دمیدن گاز در حفره شکمی در بیماران بخش جراحی زنان تحت لاپاراسکوپی JF - URMIAMJ JO - URMIAMJ VL - 33 IS - 7 UR - http://umj.umsu.ac.ir/article-1-5875-en.html Y1 - 2022 SP - 485 EP - 494 KW - Capnograghy KW - ETCO2 KW - Gynecologic Surgery KW - Laparoscopy N2 - Background & Aims: Laparoscopic surgery has been developed recently. In this method, CO2 is insufflated in peritoneal space, rises intra-abdominal pressure, and causes hemodynamic changes. Capnography and non-invasive end-tidal CO2 (ETCO2) measurement are the most important and helpful monitoring methods. Materials & Methods: In this semi-experimental study, 60 patients candidated for laparoscopic gynecological surgery were included. After induction of anesthesia by the same method, end-tidal CO2 monitoring was performed using capnography. Mean arterial pressure (MAP), and heart rate (HR) of the patients were measured in these intervals: Immediately after intratracheal intubation, before blowing CO2 into the abdominal cavity, immediately after blowing CO2 into the abdominal cavity, 10 minutes and 20 minutes after blowing gas into the abdominal cavity, 10 minutes after CO2 gas exits the abdominal cavity, and before extubation of the patient. Results: ETCO2, MAP, and HR in the 10th and 20th minutes after gas blowing, as well as before extubation were statistically higher compared to other times (P <0.05). Conclusion: According to the present study, it was concluded that end-tidal CO2 changes during laparoscopic surgery are helpful in the early diagnosis of complications, and the highest increase in end-tidal CO2 and hemodynamic changes are evident in the 10th and 20th minutes after blowing CO2 into the abdominal cavity.
