INTRODUCTIONThe most effective management of postoperative crises is prevention. This starts with preoperative preparation and patient screening. There are many factors that can be controlled and improved by the patient, including but not limited to, smoking cessation, cardiopulmonary rehab and teaching/setting peri-operative expectations. Equally as important is patient selection, which is influenced by pulmonary function tests, cardiopulmonary reserve, and pre-existing comorbidities. After the operation, the care team can also greatly improve outcomes with aggressive cardiopulmonary therapies, ambulation, vigilant monitoring and frequent assessments of the patient. Even when all of these guidelines are followed not all early complications can be avoided.A recent review of the National Cancer Database by Rosen et al found a 2.6% mortality from lobectomy [1]. Morbidity associated with lobectomy is 10% to 50%, and increases in the elderly [2]. The population being treated by thoracic surgeons continues to age and the complexity of the operations is increasing as neoadjuvant therapies become more prevalent. Early postoperative crises after lobectomy will occur, necessitating prompt and effective management strategies. The most common complications after pulmonary resection are listed below in Table 1, in this chapter we will focus on the early complications after lobectomy [3].For the purposes of this chapter we will define early post-operative crisis as those that develop within 48 hours of the operation.
AIR LEAKProlonged air leak is the most common complication after pulmonary resection, with a reported incidence of 15-18% [4]. Prolonged air leak is defined as a leak lasted more than 7 days after pulmonary resection. Cerfolio et al reported an incidence of 25% on postoperative day 1 and 20% on postoperative day 2 [5,6]

Patient factors that increase risk of developing an air leak include emphysematous lungs, larger parenchymal resection and therefore less parenchymal apposition to chest wall, and inadequate drainage of air by thoracostomy tube(s).
PREVENTION STRATEGIES1. Bronchial stump buttressing with a muscle flap. In patients with an infected pleural space or who are on chronic immunosuppression, coverage of the stump with vascularized muscle may prevent bronchial stump breakdown [7]. The intercostal muscle is an excellent coverage option and is harvested from the intercostal space upon entry into the chest at the level of the thoracotomy. It is important to plan ahead, as this muscle needs to be harvested prior to placing the rib spreader in an open operation to prevent crushing the vascular supply. Dissection is begun on the inferior rib and the muscle is mobilized using a periosteal elevator posteriorly to the paraspinous muscle. Attention is...
