Simplified Acute Physiology Score as a predictor of Expiratory Muscle Strength in individuals after discharge from the Intensive Care Unity

Abstract

Objective: To correlate SAPS III, respiratory muscle strength and palmar grip force in patients after discharge from the ICU.

Material and Methods: cross-sectional study with 21 individuals older than 18 years, with SAPS Score III duly filled in and that they were capable to perform specific tests. The instruments used for research were Simplified Acute Physiological Score (SAPS III), evaluation of respiratory muscle strength and palmar grip force until 48 hours after discharge of the patient to the hospital clinic.

Results: 11 hospitalized due to heart surgery and 10 for other types of surgery (not cardiac). The mean age of the patients was 53.90±15.96 years, with a prevalence of 52.4% of females. The group for other surgeries spent more time on mechanical ventilation and presented risk of mortality (p=0.040) and mortality for South America (p = 0.035) was significantly higher when compared to cardiac patients. In relation to peripheral muscle strength and respiratory rate was observed that palmar grip force was 118.2% of predicted for this individuals, while the PImáx was 60.9% of predicted while the PEmáx was 51.63%, indicating a decrease in both.

Conclusion: In this study it was possible to verify that the SAPS III scale may be a predictor of decreased expiratory muscle strength in surgical patients after discharge from the ICU.
