⚡ TL;DR(Too Long; Didn't Read)

Conclusion: Pneumoperitoneum created in the 12 and 14 mmHg pressure during laparoscopic cholecsytectomy, does not affect respiratory mechanics, hemodynamics and metabolism;and possible complications can be prevented by balanced general anesthesia, controlled ventilation, careful positioning and peroperative monitoring and especially careful observation during the CO2 insufflation.

Abstract

Objective: This study has targeted to compare the effects of CO2 pneumoperitoneum, generated by 12 and 14 mmHg pressure that leads to increase in intra-abdominal pressure, on ventilation dynamics, hemodynamics and metabolism in the laparoscopic cholecsytectomies. Material and Methods: Our study was carried out prospectively using the method of randomisation, after Okmeydanı Training and Research Hospital Ethics Committee approval. Totally 50 adult patients who were ASA (American Society of Anesthesiology) I-II and scheduled for elective laparoscopic cholecsytectomy, were enrolled in the study, after voluntary informed consents were obtained. Patients were divided into two groups according to CO2 pneumoperitoneum pressure generated during laparoscopic cholecsytectomy. Group I; 12 mmHg, Group II;14 mmHg. Results: Mean age of the patients enrolled in the study was 53.08±11.08, with 36 (72 %) being women and 14 (28 %) men. There were not any statistically significant difference between the two groups (p>0.05) concerning Ppeak (peak pressure), heart rate, arterial blood pressure, central venous pressure and cardiac output, arterial blood gas lactate and central venous blood gas lactate values, measured after induction, 10th minute, 20th minute and 30th minute of pneumoperitoneum and when the abdomen was closed. For the AST, ALT, GGT, ALP, LDH, total bilirubin, direct bilirubin, urea and creatinin levels preoperatively and postoperatively, statistically significant differences were not detected between the two groups (p>0.05). Bladder pressures on 10th, 20th, and 30th minute of pneumoperitoneum, were significantly statistically higher (p<0.05) in Group II in compairson to Group I but, at the abdomen closing period there was no significant difference between two groups (p>0.05). Conclusion: Pneumoperitoneum created in the 12 and 14 mmHg pressure during laparoscopic cholecsytectomy, does not affect respiratory mechanics, hemodynamics and metabolism;and possible complications can be prevented by balanced general anesthesia, controlled ventilation, careful positioning and peroperative monitoring and especially careful observation during the CO2 insufflation.

Özet

Amaç: Bu çalışmada, laparoskopik kolesistektomi operasyonlarında 12 ve 14 mmHg ile oluşturulan CO2 pnomoperitonyumunun yol açtığı intraabdominal basınç artışının solunum dinamiği, hemodinami ve metabolizma üzerindeki etkilerinin karşılaştırılması hedeflenmiştir.Gereç ve Yöntemler: Çalışmamız, S.B. Okmeydanı Eğitim ve Araştırma Hastanesi Etik Kurul onayı alındıktan sonra prospektif, randomize olarak planlanmıştır. ASA (American Society of Anesthesiology) I-II olan ve elektif laparoskopik kolesistektomi planlanan toplam 50 erişkin hasta, gönüllü olur onamları alınarak çalışmaya dâhil edilmiştir. Hastalar laparoskopik kolesistektomi sırasında oluşturulan CO2 pnomoperitonyum basınçlarına göre iki gruba ayrılmıştır. Grup I;12 mmHg, Grup II;14 mmHg.Bulgular: Çalışmamız ortalama yaşları 53.08±11.08 olan, 36'sı (% 72) kadın ve 14'ü (% 28) erkek toplam 50 olgu üzerinde yapılmıştır. İndüksiyon sonrası, pnomoperitonyumun 10. dk, 20. dk., 30. dk. ve batın kapatıldığı zamanki P tepe (tepe basıncı), kalp atım hızı, tansiyon arteryal, santral venöz basınç, kardiyak debi, arter kan gazında laktat ve santral venöz kan gazındaki laktat değerlerinde gruplar arasında istatistiksel olarak anlamlı fark bulunmamıştır (p>0.05). AST, ALT, GGT, ALP, LDH, total bilirubin, direkt bilirubin, üre ve kreatinin düzeylerinde preoperatif ve postopereatif, gruplar arasında istatistiki anlamlı fark tespit edilmemiştir (p>0.05). Pnomoperitonyumun 10. dk., 20. dk. ve 30. dk.'larındaki mesane basınçları, Grup II'de Grup I'e göre istatistiksel olarak anlamlı düzeyde yüksek (p 0.05).Sonuç: Laparoskopik kolesistektomi operasyonlarında 12 mmHg ve 14 mmHg basınçlarında oluşturulan pnomoperitonyumun, solunum mekaniği, hemodinami ve metabolizmayı etkilemediği, olası komplikasyonların dengeli genel anestezi, kontrollü solunum, dikkatli pozisyon verme, peroperatif monitörizasyon ve özellikle CO2insüflasyonu süresince dikkatli gözlem ile önlenebileceği sonucuna vardık.
