Brief Summary

The diaphragmatic pacemaker (DP) has proven its utility in replacing mechanical ventilation (MV) in patients with chronic spinal cord injury (SCI) and Amyotrophic Lateral Sclerosis (ALS), by improving the patients quality of life and reducing morbi-mortality and the associated health care costs. The anesthetic management of these patients and the particularities of the surgical procedure represent an anesthetic challenge. The objective of our study is to analyze the management and the intraoperative complications in the patients with DP in our institution.

Outcome Measures

Primary Outcomes (1)

  • all cause of morbidity

    evidence of morbity associated DP surgery: pnemothorax assessed by RX, capnothorax assessed by mecanical ventilation dificulties during surgery, arrythmia during surgery, automomic dysreflexia defined as hipertensive crisis associated to painful stimuly during surgery

    two weeks

Secondary Outcomes (1)

  • anesthetic technique

    surgery time

Study Arms (1)

Diaphragmatic Pacer

Patient that have been proposed to diaphragmatic pacer placement at our institution.

Device: Diaphragmatic Pacer

Interventions

The surgical procedure of DP implantation consists in placing four intramuscular electrodes, using a conventional abdominal laparoscopy with four ports. It consists in locating the optimum point for electrode insertion. The process involves mapping between 30 and 50 different points in each hemidiaphragm by applying an electric stimulus of 2-24 mA at 100 µsec pulse widths11. It results in both qualitative and quantitative assessment of diaphragmatic movement. Site of main electrode is identified as the location of each hemidiaphragm's change of maximum pressure and site of secondary electrode as replica of main site. Once the sites are identified intramuscular electrode placement phase is initiated. Finally the electrodes are tunneled out to the corresponding percutaneous exit site.
