BACKGROUND To evaluate the effect of pretreatment with the mixed alpha- and beta-adrenergic blocker, labetalol, on blood pressure instability during surgical resection of pheochromocytoma. METHODS Blood pressure stability and surgical results were compared between patients in the saline (n = 11) and labetalol (n = 15) groups. Anesthesia was induced with(More)
Anesthetic management of a parturient with respiratory failure associated with hemoptysis, dyspnea, and orthopnea is difficult. An anesthesiologist should realize that the patient's major problem is not solved during the surgery. This circumstance is similar to a patient with associated cardiac disease scheduled for non-cardiac surgery. General anesthesia(More)
A lumbar laminectomy is a common and routine operation. Damage to abdominal vascular structures during surgery is a relatively infrequent complication; however, when it does occur, it is sudden and life-threatening. We herein report on 2 cases of abdominal vascular injury which occurred during lumbar microdiscectomies. The first case was a 34-year-old man.(More)
OBJECTIVES To examine the effects of 17β-estradiol (E2) and progestogens, used in hormone therapy, on estrogen receptors (ER), progesterone receptors (PR), and human breast tumor cell growth. MATERIALS AND METHODS MCF-7 cells were incubated in pure E2 (1 nM and 10 nM) as well as in E2 in conjunction with 10 nM progestogens, including progesterone (P4),(More)
Prophylactic antibiotics are frequently administered during anesthesia to reduce the incidence of infection. The most common organisms revealed in wound infections are staphylococci. Vancomycin is the antibiotic of choice for resistant staphylococcal infections and bacterial endocarditis in patient allergic to penicillin. We had a case of tibial(More)
Exploration of tracheostomy is not uncommon, however, in case a patient with a facial reconstruction flap, trouble may arise because of difficulty in intubation. We hereby report a patient who had a fresh facial reconstruction flap after radical resection of buccal carcinoma, sustained bleeding around the tracheostomy and was scheduled for exploration of(More)
We report a case of unexpected malfunction of prosthetic mitral leaflets, discovered by transesophageal echocardiography (TEE) immediately after implantation, due to selection of an inappropriate size of prosthesis; the problem was amended immediately by surgical revision. The subject was a 48-year-old man admitted for mitral valve replacement because of(More)
