Bradycardia during cold ocular irrigation under general anaesthesia: an example of the diving reflex.
نویسندگان
چکیده
A case of bradycardia is reported which was precipitated by cold normal saline applied to the eye during general anaesthesia. The history and physiology of the diving reflex is discussed and we believe that these data suggest that this patient's bradycardia was induced by the diving reflex, and not by the oculocardiac reflex.

The diving reflex: bradycardia during cold ocular irrigation.
R E P L Y I thank Drs. Mezon and Badner for their thoughts on the case, but I don't think diminished gas flow in the face o f increased minute volume explains the rapid hypercarbia. Firstly, within 15 min the PETCO 2 increased from 32 to 45 mmHg without alteration o f ventilation or fresh gas flow. Secondly, I have never seen a doubling o f PETCO 2 simply by increasing the minute volume without...
متن کاملAnticholinergic premedication for prevention of oculocardiac reflex during squint surgery.
BACKGROUND Profound bradycardia during eye surgery is potentially serious event. In clinical practice this Oculocardiac Reflex (OCR) is most often encountered during squint surgery. The objective of this study was to assess the occurrence of OCR and prove the effect of anticholinergic premedication (atropine) to prevent OCR. METHODS This study comprises of sixty patients (age 2-30 years) oper...
متن کاملHypothermia, the Diving Reflex, and Survival
This paper reviews the contributions of hypothermia and the mammalian diving reflex (MDR) to human survival of cold-water immersion incidents. It also examines the relationship between the victim’s age and MDR and considers the protective role played by hypothermia. Hypothermia is the result of a reduced metabolic rate and lowered oxygen consumption by body tissues. Although hypothermia may pro...
متن کاملThe human heart rate response profiles to five vagal maneuvers.
Healthy teens and adults performed four vagotonic maneuvers. A large series of strabismus surgery patients had deliberately quantified tension on extraocular rectus muscles during general anesthesia. The mean bradycardia was greatest for diving response (apneic facial exposure to cold) and Valsalva maneuver and least for pressure on the globe and carotid sinus massage. Bradycardia occurred for ...
