Selective antegrade cerebral perfusion attenuates brain metabolic deficit in aortic arch surgery: a prospective randomized trial.

Background: Aortic arch surgery has a high incidence of brain injury. This may in part be caused by a cerebral metabolic deficit observed after hypothermic circulatory arrest (HCA). We hypothesized that selective antegrade cerebral perfusion (SACP) would attenuate this phenomenon.

Temperature monitoring during cardiopulmonary bypass--do we undercool or overheat the brain?

Objective: Brain cooling is an essential component of aortic surgery requiring circulatory arrest and inadequate cooling may lead to brain injury. Similarly, brain hyperthermia during the rewarming phase of cardiopulmonary bypass may also lead to neurological injury. Conventional temperature monitoring sites may not reflect the core brain temperature (Tdegrees).

Differential brain and body temperature during cardiopulmonary bypass--a randomised clinical study.

Objective: Maintenance of normothermia during cardiopulmonary bypass (CPB) may have advantages over hypothermia but there is a potential increased hazard of neurological injury. A novel aortic cannula (Cobra catheter, Cardeon Corp., Cupertino, CA, USA) which compartmentalises the aorta may allow simultaneous brain cooling during maintained corporeal normothermia.

Extrapleural bronchial artery ligation for life-threatening hemoptysis in cystic fibrosis--a case report.

Hemoptyses are common in cystic fibrosis (CF) patients. They range from massive life-threatening (> 240 mL/24 hours) to recurrent minor streaking. Limited pulmonary reserve, potential concurrent chest infection, and the progressive nature of CF pose a high risk to this subgroup.

A survey of patient satisfaction after day case surgery.

A prospective survey of patients attending day case surgery was undertaken to determine patient satisfaction. In an eight-week prospective study, patients undergoing procedures in the day surgical unit were asked to fill in two questionnaires, the first before surgery and the second two weeks after surgery. One hundred and eighty-nine patients were recruited into the study; of these, 98 (52.
