PURPOSE Small size needles have been regularly used for intradiscal injection of innocuous/potential therapeutic compounds in experimental conditions, but also in clinic procedures, such as discography. Our aim was to investigate if a 30-gauge needle could trigger observable changes on intact intervertebral discs. We compared these effects to those induced by a large size needle (21-gauge), a w...

AIM To compare the effect of 30-gauge vs 27-gauge needle size on intraocular pressure (IOP) rise and patients' pain experience after intravitreal injection (IVI) of bevacizumab. MATERIALS AND METHODS Cross-sectional, randomized, double-armed study. Patients were randomized to IVI with 30-gauge or 27-gauge needle. The IOP was measured pre and post IVI. Patients' pain was graded using the visua...

the pathergy phenomenon (pp) is one of the hallmarks of behcet's disease (bd). it has been reported to be positive from 17.5% to 83% of cases in different studies. pp is used as a diagnosis criterion in the dilsen criteria, the japan criteria, the international criteria, and the iran criteria. it is therefore important to know wether pp is a fix manifestation of the disease or a cyclic manifest...

The transarterial approach to brachial plexus block is a well-established method of producing anesthesia of the upper extremity. However, it is associated with a failure rate of 20% to 30%. Failure may be secondary to the common use of a relatively long needle, which can penetrate the posterior wall of the sheath and result in inadvertent injection of the local anesthetic into the surrounding t...

OBJECTIVE The study was designed to compare the insertion characteristics and incidence of PDPH between 25 gauge Quincke needle and 26 gauge Eldor needle for spinal anaesthesia in elective c/s. METHOD 60 pregnant women (aged 19-35 yrs and weighing 58 -67 kg) undergoing elective caesarean section were randomized into group A (Quincke spinal needle group) or group B (Eldor spinal needle group)....

Many dentists prefer using smaller gauge (27- or 30-gauge) needles for anesthesia injection, believing that needles with a smaller diameter result in less injection pain than wider diameter needles. For this study, three dentists in a general practice administered 930 injections to 810 adult patients using 25- and 27-gauge needles for mandibular inferior alveolar block injections and 25-, 27-, ...

We introduce a 15 cm, 26-gauge spinal needle (Steriseal Ltd, Redditch) through a standard Tuohy needle (9·6 cm, 16-gauge) which has its tip in the epidural space. Once the dura has been punctured the spinal needle is only really held in place by the dura. It is therefore quite difficult to attach the syringe of local anaesthetic and then inject without inadvertently placing the tip of the spina...

OBJECTIVES The purpose of this study is to determine the possible differences in deflection between two needles of same length and external gauge but with different internal gauges during truncal block of the inferior alveolar nerve. The initial working hypothesis was that greater deflection may be expected with larger internal gauge needles. STUDY DESIGN Four clinicians subjected 346 patient...

OBJECTIVES To compare the frequency of headache and the procedure time following lumbar puncture (LP) using a 25-gauge needle compared to a 22-gauge needle. DESIGN 4-period crossover blinded randomised controlled trial. SETTING Oncology unit, Royal Children's Hospital, Melbourne. PATIENTS Children aged 4-15 years at enrolment having LPs as part of their treatment for leukaemia. INTERVEN...
