Arterial blood gases changes in upper abdominal surgeries. A prospective study
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2016, Vol 4, Issue 4
Abstract
Abstract: Postoperative pulmonary complications (PPCs) are defined as pulmonary abnormalities occurring in postoperative period which produce clinically significant, identifiable disease or dysfunction that adversely affects the patients’ clinical course and manifests in changes in blood gases coefficients. Upper abdominal surgical procedures are associated with a high risk of postoperative pulmonary complications (PPCs) which manifest in the ABG (arterial blood gases) of the patients. Despite recent advances in preoperative management, postoperative respiratory morbidity is still a common problem especially following upper abdominal surgery. The objective is to study the risks of postoperative complications, a pre-operative medical evaluation of the patients was done by performing ABG (arterial blood gases) both pre and post operatively and study the changes in them. The Aim is to see the impact of upper abdominal surgeries (cholecystectomy or gastrectomy) on post-arterial blood gas (ABG) in elderly patients. To compare and analyse the change in ABG parameters preoperatively and post operatively. In methods we performed a randomly controlled prospective hospital study including eighty patients. Patient’s ≥ 60 years of age were taken randomly of both the sexes which were of ASA status 2 to 3, planned for elective, non-laparoscopic, upper abdominal surgeries (cholecystectomy or gastrectomy). The selected individuals were subjected to preoperative assessments and ABG preoperatively. After surgery and proper recovery from the anesthesia ABG was again carried out in the post-operative period on the first and second post-operative days as was done pre-operatively and the changes in their ABGs were noted. The results in our study arterial pH, PO2 and PCO2 were studied preoperatively and on the first and second post operative day following upper abdominal surgeries. There is change in pH, PO2 and PCO2 on the first and second post operative day following upper abdominal surgeries , the change being more on first post operative day than the second .Improvement was seen beyond the second post operative day and there-on. In conclusion the Following upper abdominal surgeries , there is change in arterial pH, PO2 and PCO2 on the first and second post operative day following upper abdominal surgeries , the change being more on first post operative day than the second in PO2 and PCO2 , not so much in the arterial pH of patients blood. Hence these ABG measurements allows patients with pulmonary abnormality to be objectively screened and could be useful for predicting operative risk related to abnormal pulmonary function. Keywords: ABG (arterial blood gases), partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2), elective upper abdominal surgery
