[Combined spinal and epidural anesthesia for laparotomy in a geriatric patient with severe obstructive lung disease].

Asthma and heavy smoking are the risk factors for postoperative respiratory distress, especially after general anesthesia. We experienced a case of sigmoidectomy in a geriatric patient with severe obstructive lung disease accompanied by asthma and a long history of smoking. The patient was a 70 year old man with 1 second volume of less than 0.6 l, because of asthma and long smoking history of 40 pieces of cigarettes a day for 50 years. We considered that general anesthesia with tracheal intubation might worsen the respiratory state after surgery and chose combined spinal and epidural anesthesia. He received sigmoidectomy under spinal anesthesia with 0.3% dibucaine 2.4 ml combined with epidural anesthesia. As the level of analgesia went up to Th4, the patient complained of dyspnea and he discharged a plenty of sputum. Without any special treatment his dyspnea disappeared spontaneously. During and after the surgery, no exacerbation occurred in his respiratory state. It is suggested that spinal anesthesia combined with epidural anesthesia is useful for a patient with severe obstructive lung disease.
