Perioperative Risk Factors

Abstract Background Postoperative pulmonary complications (PPCs) contribute significantly to overall postoperative morbidity and mortality. In abdominal surgery, PPCs remain frequent. The study aimed to analyze the profile and outcomes of PPCs in patients submitted to abdominal surgery and admitted in a Portuguese polyvalent intensive care unit. Methods From January to December 2017 in the polyvalent intensive care unit of Hospital Garcia de Orta, Almada, Portugal, we conducted a retrospective, observational study of inpatients submitted to urgent or elective abdominal surgery who had severe PPCs. We evaluated the perioperative risk factors and associated mortality. Logistic regression was performed to find which perioperative risk factors were most important in the occurrence of PPCs. Results Sixty patients (75% male) with a median age of 64.5 [47–81] years who were submitted to urgent or elective abdominal surgery were included in the analysis. Thirty-six patients (60%) developed PPCs within 48 h and twenty-four developed PPCs after 48 h. Pneumonia was the most frequent PPC in this sample. In this cohort, 48 patients developed acute respiratory failure and needed mechanical ventilation. In the emergency setting, peritonitis had the highest rate of PPCs. Electively operated patients who developed PPCs were mostly carriers of digestive malignancies. Thirty-day mortality was 21.7%. The risk of PPCs development in the first 48 h was related to the need for neuromuscular blocking drugs several times during surgery and preoperative abnormal arterial blood gases. Median abdominal surgical incision, long surgery duration, and high body mass index were associated with PPCs that occurred more than 48 h after surgery. The American Society of Anesthesiologists physical status score 4 and COPD/Asthma determined less mechanical ventilation needs since they were preoperatively optimized. Malnutrition (low albumin) before surgery was associated with 30-day mortality. Conclusion PPCs after abdominal surgery are still a major problem since they have profound effects on outcomes. Our results suggest that programs before surgery, involve preoperative lifestyle changes, such as nutritional supplementation, exercise, stress reduction, and smoking cessation, were an effective strategy in mitigating postoperative complications by decreasing mortality.

Elective Abdominal Surgery

SummaryThrombelastography has been performed on recalcified whole blood from 50 patients before, during and after elective abdominal surgery. The characteristic changes of the thrombelastographic indices r, k and mA are described.During operation r and k shortened, but no change in mA was observed. This response was in part associated with an increase in factor VIII activity. Following operation, while r time was somewhat shortened, much more marked changes in k and mA were evident. Increasing fibrinogen concentration was the dominant factor in determining the post-operative changes in the thrombelastograph.

Postoperative Mechanical Ventilation

Background: Cesarean hysterectomy is a major operation that causes massive hemorrhage and larger fluid resuscitation. Thus, postoperative mechanical ventilation support is required in some patients, involving longer hospital stay and high cost of hospital care. Objective: To find the predictive factors for postoperative respiratory support in pregnant women underwent cesarean hysterectomy. Materials and Methods: A retrospective review of patients underwent cesarean hysterectomy between January 2014 and June 2019 was conducted. Patient characteristics, anesthetic records and hospital length of stay were reviewed. The relationship between factors and postoperative mechanical ventilator (PMV) was also analyzed. Results: A total of 180 patients were included in the present study, wherein, 64 patients (35%) required PMV and 30 patients (16%) needed postoperative oxygen support. Multivariable logistic regression was used to identify the relationship between PMV and the associated factors. The authors found the American Society of Anesthesiologists (ASA) classification and the volume of intraoperative blood components replacement (packed red blood cells [PRC] and fresh frozen plasma [FFP]) were significantly related to PMV: ASA3 16.51 (95% CI 1.89 to 144.33), ASA4 183.25 (95% CI 2.92 to 11,500.65), p=0.003; PRC 1.0028 (95% CI 1.0008 to 1.0047), p=0.001; FFP 1.0022 (95% CI 1.0000 to 1.0043), p=0.029, respectively. Conclusion: Postoperative mechanical ventilation was found in one-third of the cesarean hysterectomy patients and associated with ICU admission along with increased in post-operative length of hospital stay. The ASA classification and intraoperative volume of blood components replacement were significantly associated with PMV. Factors associated significantly with respiratory support were ASA classification and duration surgery. Keywords: Factors associated; Respiratory support; Cesarean hysterectomy
