Title: [abstract] HYPERBARIC TREATMENT OF IATROGENIC AIR EMBOLISM.
Author: Massey, EW; Shelton, DL; Moon, RE; Camporesi, EM
Abstract: Air embolism (AE) may occur as a rare complication of surgical procedures. We report 14 patients (7 female) with iatrogenic AE. Age ranged from 5 to 84 years (mean 46.9 years). Seven patients had onset of deficit in the immediate perioperative period: 5 had cardiac surgery, 2 had neurosurgical procedures; 4 had invasive radiologic procedures; 1 was on dialysis and 2 cases were associated with jugular vein catheterization. All iatrogenic air embolism patients receiving hyperbaric oxygen therapy (HBO) at Duke University during the last 9 years were entered into this retrospective study. Clinical presentation included coma, diplopia, hemiparesis, seizures: most commonly a sudden focal neurologic deficit indistinguishable from other cerebral stroke syndromes. Distribution involved the middle cerebral artery in 8 patients and multiple vessels in 6 patients. In one case neurological exam had returned to normal by the time of presentation to the hyperbaric chamber. Most patients were treated with Table 6 or 6A, with extensions as required. Neurological examination was done pre-and post-therapy. Delay between AE and treatment ranged from 1.2 to 42 hours (mean 17.5 hours). Outcome included 3 deaths; 2 unchanged (= total of 5 pts not improved: mean treatment delay 19.9 ± 14 hr [SD]); 6 had major improvement by neurologic examination and in symptoms; 2 had minor improvement and 1 had complete resolution (= total of 9 pts improved: mean treatment delay 16.1 ± 13.3 hr). The difference in delay times betweeen the two groups was not statistically significant. Delay in treatment of 5 patients was >/= 24 hours. Two of the patients who had major improvement with HBO were treated at 31 and 42 hours after AE. We recommend that delay in referral should not discourage hyperbaric treatment.
