Key result
In morbidly obese patients, laparotomy provoked a significant increase in lung compliance and decrease in additional lung resistance 1 hour after the peritoneum was opened (P<0.005).
Why the study?
Does abdominal opening modify respiratory mechanics during general anesthesia in morbidly obese patients compared to normal-weight patients?
Population
19 patients undergoing laparotomy under general anesthesia.
Comparison
Abdominal opening during general anesthesia vs Normal-weight patients and closed abdomen
Design
Cohort
Follow-up
During surgery (5 time points)

p-value: p=<0.005
Abdominal opening during laparotomy significantly improves lung compliance and reduces lung resistance in morbidly obese patients under general anesthesia.
Júnior et al. (2002) conducted an observational in Morbid obesity (n=19). Abdominal opening (laparotomy) during general anesthesia vs. Normal-weight patients and baseline measurements was evaluated on Respiratory mechanics (lung and chest wall compliance and resistance) (p=<0.005). In morbidly obese patients, laparotomy provoked a significant increase in lung compliance and decrease in additional lung resistance 1 hour after the peritoneum was opened (P<0.005).
