A Novel Method for Ultrasound-Guided Central Catheter Placement-Supraclavicular Brachiocephalic Vein Catheterization Versus Jugular Catheterization: A Prospective Randomized Study.

OBJECTIVES: To assess the superiority of a novel ultrasound-guided central venous catheterization technique, supraclavicular brachiocephalic catheterization, compared to jugular vein catheterization. DESIGN: Prospective randomized trial. SETTING: Operating rooms and intensive care unit. PARTICIPANTS: Eighty-six patients with central catheter placement were included in the present study. INTERVENTIONS: In the brachiocephalic group, ultrasound-guided catheterization of the brachiocephalic vein was performed via the supraclavicular route using needle-in-plane and syringe-free techniques. In the jugular group, ultrasound-guided catheterization of the internal jugular vein was performed using the needle-out-of-plane technique. MEASUREMENTS AND MAIN RESULTS: Measurements included number of needle insertion attempts, ultrasonography times, and cannulation times. Additionally, ultrasound visibility of the veins, needle, guidewire, and catheter, as well as ease of the procedure, were assessed. Mean cannulation time was 27.65 ± 25.36 seconds in Group B and 28.16 ± 21.72 seconds in Group J. The overall success rate was 97.6% in Group B and 97.7% in Group J. The mean ease score of the cannulation procedure was 8.78 ± 1.13 in Group B and 8.67 ± 1.23 in Group J. No significant differences were detected between groups. The mean ultrasonography time was 11.98 ± 6.91 seconds in Group B and 2.88 ± 1.47 seconds in Group J. Ultrasound visibility of the brachiocephalic, jugular, and subclavian veins, as well as the needle and the guidewire, were good; however, visibility of the catheter was poor. CONCLUSIONS: Although not superior to the standard internal jugular approach, the novel supraclavicular approach proved to be a noninferior method for central venous cannulation.

Ultrasound detection of sciatic nerve movements with ankle dorsiflexion/plantar flexion: Prospective comparative study of a novel method to locate the sciatic nerve.

OBJECTIVES: It is possible to observe the in-vivo movements of nerves using real-time ultrasound. In this study, we aimed to visualize the movements of the sciatic nerve as a guide to identify the sciatic nerve to distinguish from surrounding tissue. METHODS: This trial was a prospective, cross-over comparative study. We included 25 healthy volunteers in this study. The movements of the sciatic nerve were visualized in the transverse view at popliteal and midthigh levels using ultrasonography. Anterior-posterior movements were assessed by measuring skin-to-nerve distance. The distances were measured during maximum ankle dorsiflexion, maximum plantar flexion and neutral position and compared with each other. We also evaluated the quality of dynamic (real-time) rotation/lateral movements of the sciatic nerve by assigning a subjective observer score. RESULTS: The movement of sciatic nerve was significant at popliteal region with active and passive ankle dorsiflexion which was 0.32 cm and 0.23 cm respectively (p=0.003). The movement of sciatic nerve was significant at midthigh region with active and passive ankle plantar flexion which was 0.11 cm and 0.01 cm respectively (p<0.001). Excellent rotation/lateral movement was observed in subjects at popliteal region and good rotation/lateral movement was observed at midthigh level. CONCLUSION: Sciatic nerve movement can be observed with ankle dorsiflexion and plantar flexion in the transverse plane at popliteal and midthigh locations under real time ultrasound. This preliminary study suggest that observing the movements of sciatic nerve is potentially valuable in clinical sciatic nerve blocks for facilitating the localization of the sciatic nerve.

Ultrasound guided erector spinae plane block provides effective opioid-sparing postoperative visceral pain relief after intussusception surgery: A pediatric case report.

Pediatric postoperative pain management may require a multimodal approach. Single injection erector spinae plane (ESP) block may provide prolonged opioid-sparing postoperative analgesiain pediatric patients. We present a pediatric case of ESP block for postoperative analgesia after intussusception surgery.Surgical reduction was planned for 9-month-old patient after a trial of hydrostatic enema reduction had failed.We performed ultrasound guided unilateral bi-level ESP block. ESP block provided effective postoperative visceral and somatic pain relief and opioid sparing analgesia in our case.

Lateral oblique approach for internal jugular vein catheterization: Randomized comparison of oblique and short-axis view of ultrasound-guided technique.

OBJECTIVE: The lateral oblique approach is a novel needle-in-plane technique for ultrasound-guided catheterization of the internal jugular vein. In this study, we aimed to compare the oblique approach with the classical short-axis technique for facilitating the procedure and reduction of mechanical complications. METHODS: This research was planned as a prospective study. Eighty-four open-heart surgery patients requiring a central venous catheter were randomly allocated into two groups: Oblique approach group (n=42) and short-axis group (n=42). Time to cannulate, the number of necessary puncture attempts, and frequency of carotid artery puncture, hematoma, puncture site bleeding, pneumothorax, and hemothorax in each group were recorded. Visualization of the vein and the needle using ultrasound were also evaluated by a subjective scale. RESULTS: The patient's characteristics were comparable between the two groups. The mean time of catheterization was 52.00±70.18 seconds in the oblique approach group and 40.76±49.30 seconds in short-axis group. The mean number of needle puncture attempts was 1.21±0.61 in oblique approach and 1.12±0.50 in short-axis group. The results did not differ significantly. There was an improved visualization of the needle in the oblique approach group, but this was not proved as statistically significant. CONCLUSION: The results of our study suggest that the lateral oblique approach is a safe and effective technique, which can be a strong alternative to the classical short-axis technique for ultrasound-guided catheterization of the internal jugular vein.

Ultrasound-guided supraclavicular brachiocephalic vein catheterization in children: Syringe-free in-plane technique with micro-convex probe.

Central venous catheterization of children is often a challenging procedure due to small anatomical structures. Ultrasound guidance has been shown to reduce complications and improve cannulation success as compared with the landmark-based technique. In-plane techniques allow for longitudinal visualization of the vessels and real-time visualization of needle track during its advancement. When in-plane and syringe-free techniques are combined, advancement of the guidewire can also be visualized. We aim to introduce our supraclavicular approach for brachiocephalic vein cannulation in pediatric patients. A syringe-free and in-plane technique is used to cannulate the patients. The subclavian, jugular, and the brachiocephalic veins were visualized by endocavity micro-convex ultrasound probe as a Y shape during the cannulation procedure. We present a case series of successful cannulation by using this technique.

Ultrasound-guided Lumbar Erector Spinae Plane Block For Postoperative Analgesia in Femur Fracture: A Pediatric Case Report.

The erector spinae plane (ESP) block is a recently defined regional anesthesia technique which is considered as an effective method in postoperative multimodal analgesia. ESP block is usually performed at the thoracic region in pediatric patients, but it is also possible to perform ESP block at the lumbar region. Femur fracture is one of the most common procedures especially in pediatric orthopedic surgery where postoperative pain management is essential. We aim to present a case of effective postoperative analgesia provided by ultrasound-guided lumbar ESP block in a 6-year-old patient after femur fixation surgery.

Ultrasound-guided Mid-humeral Radial Nerve Block Provides Sufficient Surgical Anesthesia at Hand Dorsum: A Novel Method and Report of Three Cases.

A peripheral nerve block is a sufficient anesthesia method for hand surgeries, as it protects the patient from the complications of general anesthesia and provides postoperative analgesia. We report the first use of an ultrasound-guided mid-humeral radial nerve block in three cases of ganglion cyst excision from hand dorsum. The block provided efficient surgical anesthesia and postoperative analgesia for the excision of ganglion cysts at the hand dorsum.

Where is the Guidewire? Confirmation of Central Catheter Placement in the Brachiocephalic Vein Using Y-shape Visualization by Ultrasound.

Central venous catheter placement with ultrasound guidance improves the success rate and reduces the number of puncture attempts and complications. Y-shape visualization of central veins using an endocavity micro-convex ultrasound probe is a new technique, which has been used for brachiocephalic vein cannulation. Since the jugular, subclavian, and brachiocephalic veins can be visualized in a single view using the Y-shape technique, it can also be used to confirm the correct placement of the catheter or guidewire. We aimed to present a case in which the location of the guidewire was verified by Y-shape visualization with an endocavity micro-convex probe after a cannulation attempt. Successful internal jugular vein catheterization was achieved with the assistance of the Y-shape imaging technique and the patient was avoided from multiple cannulation attempts.

Ultrasound-guided Erector Spinae Plane Block for the Management of Herpes Zoster Pain: Observational Study.

Background Herpes zoster is caused by the reactivation of latent varicella-zoster virus, which promotes acute and chronic pain that may interfere with daily activities and reduce the quality of life. Ultrasound-guided erector spinae plane (ESP) blocks are used for a wide variety of indications in the management of acute, chronic, and postoperative pain. Our aim was to evaluate the efficacy of ultrasound-guided erector spinae plane blocks for the management of pain in herpes zoster. Methods The medical records of 34 patients with acute or chronic pain during herpes zoster between May 2017 and June 2018 were investigated at two pain clinic centers. The patients received ultrasound-guided erector spinae plane block: We performed a single injection for the patients having acute pain and a continuous block for the patients having chronic pain. Patient characteristics, block characteristics (needle insertion level, catheter, or single insertion), the volume of given local anesthetics, the intensity of pain before and after the block procedure using a numerical rating score (NRS) between 0 and 10, and the duration of analgesia were evaluated. Results All patients reported a remarkable and rapid resolution of pain immediately after the block procedure. Median (min-max) NRS score before the block procedure was 9 (4-10). The median (min-max) NRS score was 1.5 (0-7) after the block procedure. The difference was found to be statistically significant (p<0.0001). NRS score after the third month was 1 (0-3); the difference is statistically significant (p=0.002). The median value of analgesia time (min-max) was 18 (3-24) hours. Conclusion Our preliminary experience demonstrated that an ESP block provided sufficient analgesia in acute herpetic pain. A combination of ESP block, pregabalin, and tramadol was also effective within the three-months-period after the block performance.

Combined duplication of the colon and vermiform appendix in an adult patient.

Combined duplication of the colon and vermiform appendix is one of the rare congenital anomalities of the alimentary tract. Only a few cases have been reported in the adult population. A 28-year-old man presented to the clinic with a mass in the right flank. Imaging showed only a hydronephrotic atrophic kidney. The final diagnosis was only available at exploration. Combined duplication of the tubular colon and vermiform appendix was confirmed histopathologically. The patient was treated with nephrectomy and complete resection of the duplicated colon and vermiform appendix. The patient recovered uneventfully, and has done well for the past year. This is believed to be one of the first reports of combined duplication of the tubular colon and vermiform appendix as a cause of hydronephrotic atrophic kidney in an adult patient.

The role of erythropoietin in hemorrhagic shock-induced liver and renal injury in rats.

INTRODUCTION: The aim of the present study was to evaluate the role of erythropoietin (EPO) in liver and renal injury following hemorrhagic shock (HS) after inhibition of tyrosine kinase activity in rats.. METHODS: Forty-eight Sprague-Dawley rats were assigned to six groups: (I) HS alone; (II) HS followed by retransfusion; (III) EPO and genistein followed by HS; (IV) EPO and genistein followed by HS, followed by retransfusion; (V) HS followed by EPO and genistein; and (VI) HS followed by EPO and genistein, followed by retransfusion. HS was induced for 60 minutes after withdrawal of 30% of the calculated total blood volume of each rat from the left femoral artery. Blood and tissue samples (from the kidney and liver) were obtained 60 minutes after HS in Group I, III, and V; blood and tissue samples were obtained 60 minutes after retransfusion in Group II, IV, and VI. In Group III and IV, EPO was given 60 minutes before HS, and genistein 30 minutes before HS. In Group V and VI, EPO and genistein were given 30 minutes after HS. RESULTS: Liver and renal injury were significantly attenuated with EPO and genistein administration. CONCLUSION: These results suggest that EPO is effective in attenuating liver and renal injury in HS, even with inhibition of tyrosine kinase activity with genistein.

Ultrasound-Guided Combined Interscalene-Cervical Plexus Block for Surgical Anesthesia in Clavicular Fractures: A Retrospective Observational Study.

OBJECTIVE: We aim to report our experiences regarding the implementation of the ultrasound-guided combined interscalene-cervical plexus block (CISCB) technique as a sole anesthesia method in clavicular fracture repair surgery. MATERIALS AND METHODS: Charts of patients, who underwent clavicular fracture surgery through this technique, were reviewed retrospectively. We used an in-plane ultrasound-guided single-insertion, double-injection combined interscalene-cervical plexus block technique. During the performance of each block, the block areas were visualized by using a linear transducer, and the needles were advanced by using the in-plane technique. Block success and complication rates were evaluated. RESULTS AND DISCUSSION: 12 patients underwent clavicular fracture surgery. Surgical regional anesthesia was achieved in 100% of blocks. None of the patients necessitated conversion to general anesthesia during surgery. There were no occurrences of acute complications. CONCLUSIONS: The ultrasound-guided combined interscalene-cervical plexus block was a successful and effective regional anesthesia method in clavicular fracture repair. Prospective comparative studies would report the superiority of the regional technique over general anesthesia.

Ultrasound-Guided Subclavian Vein Cannulation in Neonate via Supraclavicular Approach.

Central venous cannulation of infants may be challenging. Ultrasonography is recommended and has been found superior to classic landmark technique in pediatric central venous cannulation. The cannulation of the subclavian vein using supraclavicular approach under real-time ultrasound guidance is a novel technique. It may have advantages over ultrasound-guided jugular vein cannulation in specific patients. We report a case of 3200-gram 20-day-old anencephalic neonate who had a diffuse generalized edema. The neonate was cannulated successfully via subclavian vein using supraclavicular approach under ultrasound guidance.
