He\u2019s training his diaphragm to use an implanted pacemaker, which lets him breathe without using a ventilator. Eventually it will allow him to leave the Intensive Care Unit.<\/em><\/p>\n

Greg Hug\u2019s first breaths using his newly implanted diaphragmatic pacemaker were tough. He tired quickly, he felt breathless, and he was disappointed that he lasted only 2.5 minutes off the ventilator.<\/p>\n

But he\u2019s been training his diaphragm and getting stronger every day since July 25 when he underwent the ground-breaking surgery at The Ottawa Hospital.<\/p>\n

\u201cIt\u2019s progressing much faster than anticipated,\u201d said Hug, a patient in the General Campus Intensive Care Unit who has been dependent on a ventilator ever since a body surfing accident in February resulted in quadriplegia. By the end of August, he was using the pacemaker for up to 570 minutes per day, in many sessions. \u201cI\u2019m very pleased.\u201d<\/p>\n

\u201cThe initial results are quite promising,\u201d said Dr. James Villeneuve, the thoracic surgeon who performed the surgery under the direction of Dr. Raymond Onders from Case Western Reserve University in Cleveland, Ohio. Diaphragmatic pacemakers have been around in various forms for 30 years, but did not work well until Dr. Onders improved the technology. He travels the world teaching the surgery now. Although some have been implanted elsewhere in Canada, this was the first at The Ottawa Hospital.<\/p>\n

Dr. James Villeneuve, thoracic surgeon, implanted Greg Hug\u2019s diaphragmatic pacemaker during the July 25 surgery.<\/em><\/p>\n

Initially used with ALS patients, the pacemaker consists of a small box that the patient wears in a harness on the right side. The box is attached to pacing wires that are placed during laparoscopy through the abdominal wall and into the diaphragm. The device provides electrical stimulation that contracts the diaphragm, allowing the patient to draw breath in a way that\u2019s similar to natural breathing.<\/p>\n

\u201cTechnically, it is not a difficult procedure \u2013 the challenge was the order of operations, the unfamiliar equipment, where to best place the pacing leads, and how to program the pacemaker,\u201d said Dr. Villeneuve.<\/p>\n

Greg Hug wears the diaphragmatic pacemaker in a harness. The device is attached to pacing wires that go through the abdominal wall and into the diaphragm, delivering electrical impulses. As he trains his diaphragm, he can breathe without a ventilator for more minutes per day, and his lung capacity and oxygen saturation levels increase.<\/em><\/p>\n

Hug can\u2019t leave the ICU until he can get off the ventilator \u2013 the pacemaker should give him that freedom and help him avoid institutional care, said Intensivist Dr. John Kim, who has coordinated Hug\u2019s care in the ICU.<\/p>\n

\u201cThe surgery was a unique challenge and rewarding too, to see that you can make such a difference to his independence,\u201d said Dr. Villeneuve. \u201cIt also opens the door for other interesting questions about weaning patients from ventilators. As we see the technology evolve to temporary wires, we may be able to use them to avoid long-term intubation or help get people out of ICU sooner. It\u2019s an exciting avenue of research we\u2019ll follow as the technology evolves.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
