BACKGROUND Except for intravenous therapy, arterial access is the most common invasive procedure performed on critically ill patients. Arterial puncture is a source of pain and discomfort. Intradermal injection of lidocaine around the puncture site decreases the incidence and severity of localized pain when used before arterial puncture. OBJECTIVE To review the recommendations and studies rel...

BACKGROUND Percutaneous transvenous mitral commissurotomy (PTMC) is an effective treatment for mitral stenosis, but transseptal puncture carries a certain risk of complications. Our previous report has shown the effectiveness of phase-array intracardiac echocardiography (ICE)-guided transseptal puncture in patients with dilated left atrium undergoing PTMC. However, there are few reports compari...

Post spinal puncture headache (PSPH) is a well known complication of spinal anesthesia. It occurs after spinal anesthesia induction due to dural and arachnoid puncture and has a significant effect on the patient's postoperative well being. This manuscript is based on an observational study that runs on Babol University of Medical Sciences and review of literatures about current concepts about t...

Background: Contrast-guided axillary vein puncture has gained popularity for pacemaker and implantable cardioverter defibrillator (ICD) implantation in adults owing to its low risk profile, and could be an alternative to subclavian vein puncture, which is commonly performed in children. The Medtronic 3830 lead is a 4.1F lumenless catheter-delivered lead which may be particularly well-suited for...

In an attempt to find the least invasive, safest, easiest, and cheapest method of obtaining resting and exercise samples of arterial blood, a comparison was made between samples from an arterial needle puncture and an arterial cannula. This study demonstrated that samples of arterial blood may be obtained by radial arterial puncture both at rest and during exercise in practically all cases with...

BACKGROUND Cervical selective nerve root block (CSNRB) is a well-established, minimally invasive procedure to treat radicular cervical pain. However, the procedure is technically challenging and might lead to major complications. The objective of this study was to evaluate the feasibility of a three-dimensional puncture planning and two-dimensional laser-guidance system for CSNRB in an ex-vivo ...

BACKGROUND Even today patients who suffer from mantle cell lymphoma have a poor prognosis, especially when the CNS is involved. To confirm the diagnosis of meningeosis lymphomatosa, asservation of the liquor cerebrospinalis is necessary. During this procedure, intrathecal chemotherapy may be given if there is clinical evidence of meningeosis. If lumbar puncture cannot be performed, a lateral su...

This paper was to analyze and contrast the damage rate on the thoracic segment different position of the dorsal root ganglion(dorsal root ganglion, DRG) caused by different puncture path in radiofrequency ablation, thus the best RF target way for the thoracic segment of different types of DRG was confirmed. According to the difference of puncture and ablation damage way, 14 segmental spinal spe...

BACKGROUND Errors in the judgement of puncture level during neuraxial anaesthesia can lead to significant complications. The aim of this study was to assess, in obstetric anaesthesia, the accuracy of clinical determination of the lumbar spinal interspace level, using surface ultrasound imaging as control. METHODS At the anaesthesia follow-up visit, women who had received lumbar neuraxial anae...

AIM To study the clinical value and efficacy of computerized tomography (CT)-monitored microinvasive craniopuncture for traumatic epidural hematoma. MATERIAL AND METHODS Thirty-three cases of traumatic epidural hematoma patients were selected at our hospital. YL-1-type disposable intracranial hematoma smash needle puncture and drainage of hematoma were used under CT monitoring and urokinase w...
