Dexmedetomidine is an alpha(2) -adrenergic agonist with sedative and analgesic properties. This study aimed to investigate if the use of a continuous dexmedetomidine infusion with i.v. morphine patient-controlled analgesia (PCA) could improve postoperative analgesia while reducing opioid consumption and opioid-related side effects. ⋯ Continuous dexmedetomidine infusion may be a useful analgesic adjuvant for patients susceptible to opioid-induced respiratory depression.

Ultrasound has added a feather in the cap of the anesthesiologists as real-time nerve localization and drug deposition around the nerve structure under real-time guidance is now a reality, as the saying "seeing is believing" has been proven true with the advent of ultrasound in anesthesia. Pediatric patients are a unique group regarding their anatomical and physiological features in comparison with adults; regional blocks in adults with the anatomical landmark and surface marking are almost uniform across the adult population. ⋯ This review article describes the common peripheral blocks in pediatric patients; the readers are encouraged to gain experience by attending workshops, hands-on practice under supervision, and conduct random controlled trials pertaining to ultrasound-guided blocks in the pediatric age group. The recent literature is encouraging and further research is promising; a wide range of blocks being described in detail by many prominent experts from all over the world.

The role of the anesthesiologist is often unknown among patients. But, the situation where the anesthesiologist is uncertain of his/her function gives more cause for concern. ⋯ The current practice of anesthesia has been found wanting in several aspects. Knowledgeable discussion by anesthesiologists with surgeons as well as enlightenment of patients and their relatives about their work will improve the quality of anesthesia care remarkably. Changes in the anesthesia training curriculum to reflect these deficiencies would be helpful.

The objective of the present study was to compare the onset, degree and recovery time of sensory and motor block and hemodynamic effects of intrathecal bupivacaine alone and bupivacaine with sufentanil or butorphanol in endoscopic urological surgeries. ⋯ The analgesia was significantly prolonged in groups B and C; group C had a less-intense motor block. Complications were reduced by the addition of butorphanol, which also has a lower tendency than sufentanil to produce pruritus. Thus, this combination of butorphanol with low-dose bupivacaine is especially beneficial in the geriatric group of patients who have multiple co-morbid conditions.

The objective was to compare the ability of norepinephrine and dopamine in reversing the hemodynamic and metabolic abnormalities of septic shock using Edwards Vigileo Monitor with Flotrac Sensor. ⋯ Norepinephrine was more useful in reversing the hemodynamic and metabolic abnormalities of hyperdynamic septic shock compared to dopamine.
