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.

The Anesthesiologist provides continuous medical care before, during, and after operation to permit the surgeons to perform surgeries; sometimes quite challenging that could otherwise cause substantial threats to the patient's survival. Anesthesiologists, because of their combination of skills are uniquely qualified to care for dying patients suffering from end diseases like cancer. These skills include knowledge of analgesic and sedative pharmacology for the management of pain, awareness of perceptual alterations along with well-known skills in drug titration and experience with critically ill and highly anxious, often agitated patients under stressful circumstances. ⋯ The practice of anesthesia in Indian scenario is different as compared to the western countries. In India, the Anesthesiologists are dependent on surgeons for their work. The degree of stress faced is due to a number of factors like the type and quality of work, his/her relationship with surgeons and the support he/she receives from colleagues and family.

Dexmedetomidine, a highly selective alpha-2 agonist has been used as an adjuvant analgesic in vascular, bariatric, and thoracic surgery. We assessed the efficacy of intravenous dexmedetomidine as an analgesic adjunct to local anesthetic infiltration for control of postoperative pain in arthroscopic knee surgery. ⋯ Intravenous dexmedetomidine in combination with intraarticular bupivacaine decreased perioperative analgesic requirement in patients undergoing arthroscopic knee surgery. However, monitoring and vigilance are essential if dexmedetomidine is used as part of a multimodal analgesic regimen in view of its hemodynamic side effects.
