Clonidine added to bupivacaine prolongs the duration of anesthesia and postoperative analgesia with minimal side effects. Ropivacaine has lower lipid solubility and better safety profile as compared to bupivacaine. This study is designed to evaluate the effects of low-dose clonidine when added to hyperbaric ropivacaine. ⋯ Addition of low-dose clonidine to intrathecal hyperbaric ropivacaine causes a significant prolongation of the duration of sensory and motor blockade as well as postoperative analgesia compared with saline placebo. However, it increases the incidence of hypotension and bradycardia which can be managed with routine clinical measures.

Propofol has been used for the induction and maintenance of anesthesia. However, patients experience vascular pain during its injection. ⋯ The results indicate an effect of the lipid type on delayed pain reduction, especially propofol-MCT/LCT. On the other hand, the lidocaine decreases immediate propofol-LCT vascular pain.

Unanticipated difficult intubation can be challenging to anesthesiologists, and various bedside tests have been tried to predict difficult intubation. ⋯ The diagnostic accuracy of NC/TM ratio and Mallampatti score were better compared to other bedside tests to predict difficult intubation in Indian population.

Laryngeal mask airway supreme (LMA-S) has an inflatable cuff while i-gel has a noninflatable cuff made of thermoplastic elastomer. ⋯ Both devices are suitable for positive pressure ventilation (PPV) in anesthetized paralyzed patients. However, i-gel gives a better laryngeal seal when compared to LMA-S and may be chosen preferentially for PPV.

Dexmedetomidine and clonidine are commonly used drugs for sedation during regional anesthesia. However, data regarding arousal time from sedation with these drugs is sparse. Hence, we designed a study to compare arousal time from sedation with dexmedetomidine and clonidine during spinal anesthesia. We also tried to find out the correlation between clinical and objective method used for assessing the depth of sedation. ⋯ Intravenous dexmedetomidine infusion has shorter arousal time from sedation than clonidine during spinal anesthesia. A strong correlation exists between BIS and RSS during recovery from sedation.
