Why Can a Patient Go into a COMA during Surgery ? Dr. Abhishek Shukla (Geriatrician) Explained: Ridhima Sharma, a law student, asked Dr. Abhishek Shukla about her 42-year-old aunt who underwent surgery for gallstones after an ultrasound confirmed gallbladder stones. Although the operation was completed, she never regained consciousness and has remained in a coma. Dr. Shukla explained that gallbladder removal (cholecystectomy) is commonly performed through laparoscopic (keyhole), open, or robotic surgery. While it is generally considered a safe procedure, no surgery is entirely free from risk. The most important possibility is cardiac arrest during surgery. If the heart stops pumping, blood flow to the brain ceases. Within 4–6 minutes, irreversible brain injury may begin despite successful CPR and restoration of the heartbeat. The patient may survive but remain in a coma due to severe hypoxic brain damage. Several factors can trigger such a catastrophe. These include complications related to anesthesia, severe allergic (anaphylactic) reactions, massive blood loss leading to hypovolemic shock, dangerously low oxygen levels (hypoxia), life-threatening heart rhythm disturbances such as ventricular tachycardia or ventricular fibrillation, electrolyte abnormalities, pulmonary embolism, tension pneumothorax, or drug-related toxicity. Dr. Shukla emphasized the importance of remembering the reversible causes of cardiac arrest using the 4 Hs—Hypoxia, Hypovolemia, Hydrogen ion (acidosis), and Hypo-/Hyperkalemia—and the 4 Ts—Toxins, Cardiac Tamponade, Tension Pneumothorax, and Thrombosis. The key message is that every patient scheduled for surgery should undergo a thorough Pre-Anesthesia Check-up (PAC). A detailed medical history, careful cardiac evaluation, and assessment for underlying heart disease, breathing problems, valve disorders, or previous allergies are essential. Identifying these hidden risks before surgery significantly reduces the likelihood of devastating complications and helps ensure the safest possible outcome for every patient. #Coma #ComaRecovery #BrainInjury #TraumaticBrainInjury #TBI #neurology #ComaSurvivor #MedicalMiracle #HopeAndHealing #recoveryjourney #Surgery #Surgeon #SurgicalLife #PostOp #PostOpRecovery #OperatingRoom #GallbladderSurgery #Cholecystectomy #LaparoscopicSurgery #LapChole #GI #gastroenterology #GallbladderHealth #DigestiveHealth #LiverHealth #wellness
