Asthma and Surgery Surgery may present several problems for asthmatics and must be approached carefully. To avoid complications there should be close communication prior to the procedure between the surgeon and the physician responsible for managing the patient's asthma. Possible Complications Complications may arise from several sources in patients with asthma who undergo surgery. When general anesthesia is required, the windpipe is intubated with a tube connected to a respirator. Under anesthesia, the respirator provides mechanical breathing and ensures the exchange of oxygen and carbon dioxide. In asthma patients, intubating the windpipe may trigger reflexes originating in the throat that can lead to bronchoconstriction. no deposit casino free bonus download blackjack games casino slot machine online win formula 1 gambling user manual samsung blackjack
