Comparative Study Clinical Trial Controlled Clinical Trial
Local anaesthetic for minor oral surgical procedures. Review.
Pain following any surgical procedure is difficult to combat by man. Analgesics can be given for some amount of symptomatic relief. The need for a long lasting local anaesthetic is with the intention to reduce the most severe nature of pain, and decrease the analgesic consumption. ⋯ This is not sufficient since the most severe nature of pain is felt six to eight hours post surgery, where as Bupivacaine has duration of action of seven to eight hours. Hence the post operative pain experienced following administration of bupivacaine was found to be considerably lesser in degree than compared to the lidocaine group. To avoid severe pain and discomfort to the patient following any minor oral surgical, the use of bupivacaine is recommended.

Sciatic nerve blockade with lipid-protein-sugar particles containing bupivacaine.
To assess the efficacy of lipid-protein-sugar particles (LPSPs) in providing prolonged duration local anesthesia by percutaneous injection. ⋯ LPSPs provide sensory blockade durations comparable to those from PLGA microspheres, with a smaller amount of drug loading. Motor blockade is shorter with LPSPs than with PLGA microspheres. LPSPs appear to be suitable for extended nerve blockade. Given their size and low density, they may be useful for topical anesthesia of the airway.

A 72-year-old female with severe heart failure due to rheumatoid myocarditis underwent open reduction of the left femoral neck (trochanteric) fracture. We performed psoas compartment block (PCB) at L3/4 level in the lateral position with the fractured side up, using a 22 G Tuohy needle to inject 10 ml of normal saline and 20 ml of 2% mepivacaine. ⋯ The patient did favorably during and after the operation. We conclude that PCB is useful for surgery of the lower extremity in patients with heart failure.

Combining regional and general anaesthesia can have many advantages, particularly in patients undergoing major thoracic, abdominal or orthopaedic surgery. The use of regional anaesthetic techniques in anaesthetized children is an accepted standard of care, because needle and procedure phobias are very common and can result in severe anxiety, an inability to cooperate and sudden unpredictable movement. Epidural local anaesthetics have the potential of attenuating sympathetic hyperactivity, maintaining bowel peristalsis, sparing the use of opioids, and facilitating postoperative feeding and out-of-bed activity. ⋯ The present review focuses on the use of a combination of regional and general anaesthesia for a variety of surgical procedures. It also compares the two anaesthetic techniques in elderly patients. The review is based on studies published during the past year.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of superficial versus combined (superficial and deep) cervical plexus block for carotid endarterectomy: a prospective, randomized study.
Carotid endarterectomy may be performed by using cervical plexus blockade with local anesthetic supplementation by the surgeon during surgery. Most practitioners use either a superficial cervical plexus block or a combined (superficial and deep) block, but it is unclear which offers the best operative conditions or greatest patient satisfaction. We compared the two techniques in patients undergoing carotid endarterectomy. ⋯ The median time to first analgesia in the superficial block group was 150 min, more than in the combined block group (median time 45 min) but this difference, although large, was not statistically significant (Mann-Whitney U-test). We found no significant differences between the anesthetic techniques studied. All patients reported satisfaction with the techniques.
