Abstract
Hypotension and bradycardia after application of suction to a subgaleal drain, or stimulus inside or outside the skull, have been reported in the medical literature. The commonly reported occurrence is stimulation of the Trigeminal nerve along its distribution and is the main factor that sets off the whole reflex arc through the Vagus nerve ending in a series of serious hemodynamic changes that institute severe bradycardia, asystole and severe hypotension. Another less common but possible patho logy caused by a suction drain is Pseudo-Hypoxic Brain Swelling (PHBS). We report a case of transient cardiac arrest after the application of theatre suction to a subgaleal drain at the closure of an uneventful craniotomy and discuss the possibilities as well as review the literature.
