PURPOSE Cerebral vasospasm (CVS) is a major complication after subarachnoid hemorrhage (SAH) induced by the rupture of intracranial aneurysms. The aim of the present study was to investigate the effect and mechanism of cervical sympathetic block on cerebral vasospasm of the rabbits after SAH. METHODS After successful modeling of cervical sympathetic block, 18 healthy male white rabbits were r...

Although local anesthesia usually is used in surgical procedures, field or nerve blocks can provide more effective anesthesia in some situations. In a field block, local anesthetic is infiltrated around the border of the surgical field, leaving the operative area undisturbed. In field blocks, epinephrine may be added to the anesthetic to enhance vasoconstriction and prolong the duration of anes...

Background and Aim: The Gow-Gates (GG) block and the inferior alveolar nerve block (IANB) can be used interchangeably for anesthetizing mandibular molars. The aim of this study was to compare these two injections in root canal therapy of mandibular molars with regard to heart rate (HR) and blood oxygen saturation (BOS) changes. Materials and Methods: Thirty patients between the ages of 18-70 y...

AIMS A prospective, randomised, double blind study was used to investigate the effect of hyaluronidase on the quality of block achieved with sub-Tenon's local anaesthesia. METHODS 150 patients scheduled for elective cataract surgery were randomly allocated to either sub-Tenon's block with 3 ml lignocaine 2%/adrenaline 1:200 000 alone or with the addition of 30 IU/ml of hyaluronidase. The bloc...

OBJECTIVES The purpose of this study was to compare the effect of PSA block injection with infiltration technique regarding local anesthesia for surgical extraction of upper third molar. MATERIAL AND METHODS A prospective, intra individual, single-blind randomized controlled trial was designed to study the severity of pain during injection and after surgical extraction of the bilaterally and ...

SUMMARY Among the many advances in local anesthesia of the hand, some of the most significant changes in the last 5 years have been the following: (1) the acceptance of safety of locally infiltrated epinephrine with lidocaine for hemostasis, which has removed the need for sedation, brachial plexus blocks, and general anesthesia for most common hand surgery operations and minor hand trauma. (2) ...

We report a case of immediate reproducible and reflexive response of asystole upon stimulation of Onyx injection during embolization of a tentorial dural arteriovenous fistula in a 53-year-old man. Upon recognition of the reflexive relationship between Onyx injection and increased vagal tone, the patient was given anticholinergic in an effort to block cholinergic hyperactivity. After atropine w...

BACKGROUND AND PURPOSE Image-guided selective nerve root block/steroid injection is commonly performed for lumbar radiculopathy. The purpose of this study was to evaluate the clinical/imaging characteristics and injection response of adjacent double-root contributions to unilateral lumbar radiculopathy in a typical interventional spine practice. MATERIALS AND METHODS In 132 of 350 patients (3...

It is known fact that adding adrenaline to local anesthetic gives many advantages but it not practiced commonly in digital anaesthesia due fear of ischemia resultant vasoconstriction. Total five cases were there. All patients received lignocaine with block. Recent literature and our findings both suggest use at least a well perfused finger safe may give some potential advantages.
