Anesthesia, essays and researches

Preanesthesia assessment is an important aspect of patient care. If a patient shows lack of interest during preanesthesia check-up or tries to rush through, it may result in incomplete history and general physical examination, compromising patient care. ⋯ Patients had insufficient knowledge about preanesthesia assessment and its role in improving the outcome of surgery.

The spinal anesthesia has the definitive advantage that profound nerve block can be produced in a large part of the body by the relatively simple injection of a small amount of local anesthetic. ⋯ The addition of magnesium sulfate in the two different doses (50, 100 mg) does not affect the quality of block or duration of analgesia. However, M 100 is as effective as fentanyl as far as the duration of analgesia is concerned.

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.
