Anesthesia, essays and researches

Maxillofacial trauma is an apt example of a difficult airway. The anesthesiologist faces challenges in their management at every step from airway access to maintenance of anesthesia and extubation and postoperative care. ⋯ Maxillofacial injuries present a complex challenge to the anaesthesiologist. The fibreoptic bronchoscope is the main weapon available in our arsenal. The submental technique scores over the time-honored tracheostomy. Communication between the anaesthesiologist and the surgeon must be given paramount importance.

The aim of the study was to compare postoperative pain relief in patients undergoing an elective thoracotomy with thoracic epidural analgesia using single shot magnesium and clonidine as adjuvants to bupivacaine. ⋯ Thoracic epidural analgesia using bupivacaine with clonidine is an efficient therapeutic modality for postthoracotomy pain. Magnesium as an adjuvant provided quality postoperative analgesia decreasing the need for postoperative rescue analgesia and incidence of postoperative shivering without causing sedation.

Although mephentermine (Termin) and ephedrine are commonly used drugs for the treatment of hypotension during anesthesia but their abuse have markedly increased, especially in the young population due to its stimulant properties. Here, we report a case of 23-year-old man with a history of chronic mephentermine abuse, posted for Achilles tendon repair under spinal anesthesia. During intraoperative period, spinal induced hypotension showed unusual resistance to ephedrine boluses and was managed by using directly acting vasoconstrictor, that is, phenylephrine.

Laryngoscopy and intubation cause an intense reflex increase in heart rate, blood pressure, due to an increased sympathoadrenal pressor response. Lignoocaine has shown blunting of pressor response to intubation. Dexmedetomidine has sympatholytic effects. ⋯ We conclude that dexmedetomidine 1μg/kg adequately attenuates the hemodynamic response to laryngoscopy and endotracheal intubation when compared with dexmedetomidine 0.5μg/kg and lignocaine 1.5mg/kg.

Intrathecal neostigmine and magnesium sulfate (MgSO4) produce substantial antinociception, potentiate analgesia of bupivacaine without neurotoxicity. ⋯ Intrathecal Neostigmine and MgSo4 does not affect characteristics of SA. Postoperative analgesia of neostigmine was better than MgSO4. Neostigmine provides some protection against hypotension of SA whereas MgSO4 protects against bradycardia.
