Identification of respiratory risk parameters among obese oral surgical patients

There is a known significant increase in perioperative complications among obese patients. Oral surgeries of obese patients under general endotracheal anesthesia pose a special challenge. The aim of the study was to evaluate postoperative pulmonary complications (PPC) risk, preoperative dyspnea score and their correlation with body mass index (BMI) among obese patients scheduled for oral surgical procedures under general anesthesia. Following the permission of the Ethics Committee and signed written informed consent, 75 obese patients (30-65 year old and ASA status II-III) were involved. PPC risk was determineted by ARISCAT score, dyspnea by Modified Borg score. The average BMI was 35.6 (SD 5.6), with no gender difference. Patients had an abdominal obesity type with an average waist to hip (W/H) ratio greater than 1.1 (women 0.99 +/- 0.19, males 1.11 +/- 0.18). The mean value of the neck size was 54.2 (SD 6.9) cm, significantly higher in males (p = 0.003). There was significant positive correlation of Ariscat scor (r=0, 57 ; p=0, 001) and preoperative degree of dyspnea (r=0, 51 ; p=0, 001) with the BMI, as well as neck circumferences with W/H ratio (r=0, 37, p=0, 01). The results showed a positive correlation of determinated risk for PPC with preoperative dyspnea level (r=0, 34 ; p=0, 002). Identification of respiratory risk parameters among obese patients and their interdependence proved to be of clinical interest. Preoperative assessment of PPC and dyspnea level at rest should be a part of a standard preoperative protocol for oralsurgical procedures especially in one-day surgery.
