Association between early pulmonary complications after abdominal surgery and preoperative physical capacity.

: To investigate whether early postoperative pulmonary complications after abdominal surgery are associated with a lower performance in preoperative six-minute walk test.: A cross-sectional cohort study of 50 participants who underwent elective abdominal surgery and performed the six-minute walk test within 48 hours prior to surgery were conducted. Postoperative pulmonary complications up to the seventh postoperative day were obtained from medical records.

Pulmonary function and physical performance outcomes with preoperative physical therapy in upper abdominal surgery: a randomized controlled trial.

Objective: Investigation of the effects of preoperative physical therapy on pulmonary function and physical performance before and after upper abdominal surgery.

Design: Non-blind randomized controlled trial.

Setting: Tertiary public hospital and private university, São Paulo state, Brazil.

Lung injury and mechanical ventilation in cardiac surgery: a review.

Respiratory failure after cardiopulmonary bypass heart surgery can result from many pre-, intra- or postoperative respiratory system-related factors. This review was aimed to discuss some factors related to acute lung injury observed during the postoperative period of cardiac surgery and the mechanical ventilation modalities which should be considered to prevent hypoxemia.

[The influence of early tracheostomy in the weaning of patients with severe traumatic brain injury].

Background And Objectives: Actually, It’s doubtful if early tracheostomy (ET) can influence mechanical ventilation (MV) weaning time or the hospital length of stay in patients with traumatic brain injury (TBI). The main objective of this trial was to verify the influence of ET on weaning time of patients with severe TBI.

Methods: Prospective, observational study, including 33 patients with severe TBI (GCS < 10 at hospital admission), evaluated according to tracheostomy performance time (early: t < 6 days; intermediate: t = 7 to 11 days; and late: t > 12 days) and the weaning from MV.
