A complete regional anesthesia technique for cardiac pacemaker insertion.
Sixteen consecutive adult patients scheduled for permanent transvenous cardiac pacemaker insertion received as their total anesthetic the combination of a cervical plexus block and blocks of the second, third, and fourth intercostal nerves using a combination of 1% mepivacaine and 0.2% tetracaine with epinephrine, 1:200,000. This technique consistently provided complete surgical anesthesia of the third cervical (C3) through the fourth thoracic (T4) dermatomes, without anesthesia of the brachial plexus. ⋯ In contrast to other reports, this technique provides surgical anesthesia that is adequate for all of the approaches used for transvenous pacemaker implantation, except for placement of a battery in an abdominal pouch. There were no serious complications and/or side effects in any of the patients studied.

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative analgesia after triple nerve block for fractured neck of femur.
Fifty patients with fractured neck of femur that required surgical correction with either a compression screw or pin and plate device were randomly allocated to receive one of two anaesthetic techniques, general anaesthesia combined with either opioid supplementation or triple nerve block (three in one block) with subcostal nerve block. The nerve blocks significantly reduced the quantity of opioid administered after operation; 48% of these patients required no additional analgesia in the first 24 hours. Plasma prilocaine levels in these patients were well below the toxic threshold, and peak absorption occurred 20 minutes after the injection. No untoward sequelae were associated with the nerve blocks.

Case ReportsMaxillary nerve block anaesthesia via the greater palatine canal: a modified technique and case reports.
A modification of the technique of maxillary nerve block (via the greater palatine canal) is discussed. This technique has been employed in the Exodontia and Oral Surgery Clinics of the United Dental Hospital of Sydney for more than 40 years. Clinical experience in that time has shown that once the greater palatine canal has been negotiated successfully, the palatal canal approach to the maxillary nerve is safe and reliable. The value of being able to anaesthetize the maxillary nerve and its branches is illustrated by the presentation of two clinical cases where local anaesthesia was achieved and the extractions performed in patients who would otherwise have required a general anaesthetic for the procedures.

An assessment of local anaesthetic blockade of the lateral femoral cutaneous nerve using a standard technique was made. The rate of successful blockade was high, but the area of sensory loss was inconsistent between patients and was more anterior and distal than described in textbooks of anatomy.
