Anesthesia for deep hypothermic circulatory arrest in adults: experience with the first 50 patients.
To evaluate the efficacy of a simple method of central nervous system (CNS) protection in patients undergoing deep hypothermic circulatory arrest (DHCA) lasting less than 30 minutes, for a variety of complex cardiovascular procedures. ⋯ The anesthetic management of DHCA described is simple, effective, and safe, and can be performed in any institution that performs cardiac surgery.

Simultaneous transesophageal atrial pacing and transesophageal echocardiography in cardiac surgical patients.
To measure the effect of inserting a transesophageal echocardiography (TEE) probe on the pacing threshold of a previously inserted transesophageal pacing stethoscope, and to examine whether an indwelling pacing stethoscope influences the feasibility and image quality of a TEE examination. ⋯ Placement of a TEE probe results in a modest increase of the transesophageal pacing threshold. An indwelling pacing stethoscope frequently interferes with the ability to perform a full echocardiographic examination, and probe manipulation commonly causes loss of pacing.

Comparative StudyShort atrioventricular delay dual-chamber pacing early after coronary artery bypass grafting in patients with poor left ventricular function.
To investigate the effect of short atrioventricular (AV) delay dual-chamber pacing on mean arterial pressure (MAP) and stroke volume index (SVI) in patients with poor left ventricular (LV) function after cardiac surgery. ⋯ Dual-chamber pacing with nonphysiologic short AV delay failed to improve acute hemodynamics in patients with poor LV function after CABG. Short AV delay VDD pacing was superior to DDD pacing in both normal and impaired LV function. The use of Doppler echocardiography enabled optimization of the AV delay on the basis of LV filling patterns.
