A microcomputer system for the practising cardiac surgeon.

The authors present a computer program designed for the practising cardiac surgeon who wishes to computerize patient data. The program is efficient, versatile and can be adapted to individual needs. It can be used with any IBM PC-compatible machine and requires little knowledge of computer science. More than 250 items on 30 000 patients can be stored and all this information analysed simultaneously. The program can chart a patient's profile and tabulate the information of the entire registry. It can generate lists of patients with their surgeons, cardiologists, diagnoses, operations and dates of intervention. It can also be used for mailing purposes.

Upper extremity neuropathies following median sternotomy.

The status of 958 patients who underwent median sternotomy between January, 1978, and May, 1981, was analyzed. Fifty-four patients had an upper extremity neuropathy. Among 38 patients who underwent further evaluation, motor and sensory nerve conduction studies localized the injury to the level of the elbow in 13, to the brachial plexus in 10, and to both locations in 6. Ninety-two percent of these 38 patients were asymptomatic 3 months after operation.

Temporary cardiac pacing following open-heart surgery.

The type, frequency and duration of use of temporary pacemaker wires were recorded in 100 patients who underwent in 100 patients who underwent open-heart surgery. Sixty-five patients had wires implanted: 29 were atrioventricular 35 ventricular and 1 atrial. Pacing was required in 24 instances for nodal rhythm, sinus bradycardia, sinus arrest, atrioventricular block or ventricular tachycardia. Patients who required a pacemaker temporarily had a significantly (P less than 0.001) longer cross-clamping time and required a significantly (P less than 0.025) larger volume of cardioplegic agent during the operation. Two patients who did not have wires placed could have benefited from pacing. Temporary pacemaker wires should always be implanted in patients after they have undergone open-heart surgery, especially when abnormal rhythms are present, or the cross-clamping time is prolonged and when larger volumes of cardioplegic agent have been used.
