Anesthetic management of pheochromocytoma is complicated and challenging. Extra-adrenal pheochromocytoma is a rare neuroendocrine tumor that produces, stores and secretes catecholamines. The main-stay in the management of pheochromocytoma surgeries is Preoperative preparation which has improved perioperative outcome. ⋯ Resection of the tumor results in acute withdrawal of catecholamines, which may lead to severe hypotension. In perioperative period, adequate hydration should be maintained. Beta-blockers, nitroglycerine, sodium nitroprusside and phenylephrine are required to avoid hemodynamic fluctuations and should be used appropriately.

Alpha-2 adrenergic agonists clonidine and dexmedetomidine, are well known to produce analgesia through an opioid independent mechanism. Alpha-2 agonists are used as an adjuvant to local anesthetic agents to extend the duration of spinal, epidural and brachial plexus blocks. ⋯ The addition of dexmedetomidine to low dose ropivacaine for CEA could shorten the onset of sensory block and extend the duration of analgesia with optimum sedation without episodes of hypoxemia as compared to addition of clonidine to ropivacaine.

The management of cardiac arrest in pregnancy is an important task for the emergency physicians. Some reasons for cardiac arrest are reversible and should be recognized and managed promptly. Cardiopulmonary resuscitation follows general advanced cardiac life support guidelines with several modifications for pregnant women, taking into account the lives of both mother and fetus. Here, we present the case of 23-year-old pregnant patient who came to Guru Nanak Dev Hospital, Amritsar; in shock, had a cardiac arrest, successfully resuscitated in Intensive Care Unit (ICU), delivered by emergency cesarean section and was discharged from ICU on 9(th) day in healthy state.
