Anesthesia, essays and researches

Open surgical procedures are associated with substantial postoperative pain; an alternative method providing adequate pain relief with minimal side effects is very much required. ⋯ Continuous thoracic PVB is as effective as continuous thoracic EA in providing pain relief in patients undergoing open nephrectomy in the postoperative period. The side effect profile of the two techniques was also similar.

Peripheral nerve blocks have become an increasingly popular form of anesthesia. Preemptive analgesia reduces central sensitization, postoperative pain, and analgesic consumption. Different additive has been used to prolong regional blockade and improve postoperative analgesia. ⋯ The addition of dexamethasone to ropivacaine improved preemptive ankle block analgesia by decreasing postoperative pain intensity and analgesic consumption with minimal postoperative complication.

Brachial plexus blockade is a time-tested technique for upper limb surgeries. The classical approach using paresthesia technique is a blind technique and may be associated with a higher failure rate and injury to the nerves and surrounding structures. To avoid some of these problems, use of peripheral nerve stimulator and ultrasound techniques were started which allowed better localization of the nerve/plexus. Ultrasound for supraclavicular brachial plexus block has improved the success rate of the block with excellent localization as well as improved safety margin. Hence, this study was planned for comparing the efficacy of conventional supraclavicular brachial plexus block with ultrasound-guided technique. ⋯ Ultrasound guidance is the safe and effective method for the supraclavicular brachial plexus block. Incidence of complications are less as ultrasound provides real-time visulaization of underlying structures and the spread of local anaesthetic.

This study aimed to evaluate the relative efficacy of prophylactic intravenous (IV) clonidine and tramadol for control of intraoperative shivering following spinal anesthesia. ⋯ Prophylactic administration of both tramadol and clonidine is effective for controlling shivering under spinal anesthesia. However, tramadol is better because of higher response rate, less sedation, and lesser hemodynamic alterations.

Epidural administration of neostigmine appears to be safe in the obstetric population. Recently, few studies have concluded 10 μg sufentanil to be an effective adjuvant with epidural neostigmine in providing labor analgesia. However, no study has evaluated the analgesic effect of epidural butorphanol with neostigmine for the same. ⋯ Epidural combination of sufentanil with neostigmine provided better pain relief in terms of the total duration of analgesia and the reduction in VAS pain scores at various time points in the initial 30 min of epidural administration of drugs during the first stage of labor in parturient when compared to the epidural combination of butorphanol with neostigmine.
