Anesthesia, essays and researches

Ultrasound-guided transversus abdominis plane (TAP) block has been proven as a safe and effective analgesic technique for several lower abdominal surgeries. Various adjuvants have been used to intensify the quality and prolong the local anesthetic effect. We evaluated the analgesic efficacy of dexamethasone addition to ropivacaine in TAP block following open abdominal hysterectomy. ⋯ Addition of dexamethasone to ropivacaine TAP block prolonged the postoperative analgesia and reduced analgesic requirement following abdominal hysterectomy.

Postoperative sore throat (POST) is a complication that is unresolved in patients undergoing endotracheal intubation. ⋯ Nebulization with ketamine 50 mg and magnesium sulfate 500 mg, 15 min before induction of general anesthesia and intubation, reduce the incidence and severity of POST and hoarseness of voice.

The postdural puncture headache (PDPH) and postdural puncture backache (PDPB) are well-known complications of spinal anesthesia. There are some attempts to reduce the frequency of complication such as different design of the spinal needles. ⋯ The incidence of complication rates and technical handling characteristics did not differ between two groups. Quincke needle is cheaper than Atracaun needle, so it can be a cost-effective choice in obstetric patients.

Benefits of regional anesthesia can be prolonged by adding adjuvants to local anesthetics. This study was designed to test the efficacy of adding nalbuphine to bupivacaine in supraclavicular brachial plexus blockade using ultrasound (US) guidance. ⋯ Nalbuphine when added to bupivacaine as an adjuvant in supraclavicular block significantly shortened the onset of sensory and motor block and enhanced the duration of sensory and motor block and DOA.

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.
