ABSTRACT
BACKGROUND:
Postoperative desaturation in older individuals is rarely addressed in the literature. The objective of this retrospective study was to investigate whether a preoperative spirometric test and arterial blood gas analysis (ABGA) might predict postoperative desaturation after spinal anesthesia in extreme older patients.METHODS:
The medical records of 399 patients (age ≥ 80 yrs) who were administered spinal anesthesia for a femur neck fracture surgery were retrospectively reviewed. Early postoperative desaturation was defined as a reduction of oxygen saturation (SpO2) below 90% within 3 days of surgery, despite O2 supply via a nasal prong. Binary logistic regression analysis was used to identify predictors of early postoperative desaturation.RESULTS:
The incidence of postoperative desaturation was 12.5%. Major morbidity rate was significantly higher in the desaturation group (n = 50) than that in the non-desaturation group (n = 349) (14% vs. 3.2%, P = 0.001) with more frequent postoperative stays in the intensive care unit (22% vs. 12%, P = 0.004). In a binary logistic regression analysis, preoperative ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2 ratio) (OR, 0.972; 95% CI 0.952-0.993; P = 0.010) and history of cardiovascular disease (OR, 2.127; 95% CI 1.004-4.507; P = 0.049) predicted postoperative desaturation.CONCLUSIONS:
Preoperative PaO2/FiO2 ratio, but not preoperative spirometry, was predictive of the postoperative desaturation in older patients after being administered spinal anesthesia for femur fracture surgery. Based on our results, preoperative ABGA may be helpful in predicting early postoperative desaturation in these patients.Mots clés
