OBJECTIVES: The glymphatic system is a recently hypothesized waste clearance system of the brain in which perivascular space constitutes a pathway similar to the lymphatic system in other body regions. Sleep and anesthesia are reported to influence the activity of the glymphatic system. Because rats are nocturnal animals, the glymphatic system is expected to be more active during the day. We attempted to elucidate the influence of the glymphatic system for intravenously injected gadodiamide in the rat brain by 2 experiments...

Ultrasound (US)-guided transversalis fascia plane block (TFPB) was first described by Hebbard as a technique for blockade of T12-L1 nerves. Although this technique appears similar to the quadratus lumborum 1 block, the point of injection is more caudal and anterior, specifically targeting ilioinguinal and iliohypogastric nerves. There are only few published data on US-guided TFPB demonstrating effective postoperative analgesia in iliac crest bone graft harvesting. We report the use of US-guided TFPB in a patient undergoing inguinal herniorrhaphy...

INTRODUCTION: The objective was to determine the ablation size of a single 15-min freeze and compare it with the conventional 10-min freeze-8-min thaw-10-min freeze protocol. Secondary objectives were to determine the ablation margin and to ascertain whether islands of viable tissue remain within the ablation zone. MATERIALS AND METHODS: Five adult swine under general anesthesia were used. After surgical abdominal exposure, two ablations were performed in liver and two in kidney...

Significant variations exist in the occurrence, form, and position of supraorbital nerve exits through the frontal bone. Detailed knowledge of the positional variations of supraorbital exits is important to ensure safe and successful regional anesthesia, and to avoid iatrogenic nerve injuries during surgery of the orbitofacial region. Supraorbital nerve exits from 116 sides of 58 dry intact adult skulls (37 male and 21 female) in a Sri Lankan population were examined to determine the morphological features and the precise position in relation to the facial midline, temporal crest of frontal bone, and frontozygomatic suture...

Renal tubular acidosis (RTA) with hypokalemia may precipitate acute respiratory failure and potentially fatal arrhythmias like ventricular fibrillation. Though there are random reports of respiratory failure needing mechanical ventilation and sudden death in patients with RTA and hypokalemia, the anesthetic management of these patients has not been clearly elucidated. Acidosis and hypokalemia have significant interactions with both general and local anesthetics and alter their effect substantially. Proper preoperative planning and optimization are required for the safe conduct of anesthesia in this subset of patients...

Patients with Duchenne muscular dystrophy (DMD) often have systemic manifestations with comorbid involvement of the cardiac and respiratory systems that increase the risk of anesthetic and perioperative morbidity. These patients frequently develop progressive myocardial involvement with cardiomyopathy, depressed cardiac function, and arrhythmias. The latter may necessitate the placement of an automatic implantable cardioverter defibrillator (AICD) insertion. As a means of avoiding the need for general anesthesia and its inherent potential of morbidity, regional anesthesia may be used in specific cases...

There are no reports for anosmia after caudal epidural steroid injections (CESIs). General anesthesia is among the reasons, but the reports up to date are extremely limited. There are no identifiable factors contributing to anosmia after epidural injection, so it is worth discussing. We present the case of a 50-year-old woman with no previous history of any sensory deficits. She experienced anosmia after CESI that had been performed due to her chronic low back pain and lasted for 4 months. Clinical and imaging studies did not reveal any pathology...

Aims: Dexmedetomidine is very dynamic drug, used for analgesia, sedation, blunting the laryngoscopic responses and as adjuvants in regional anesthesia. Studies have shown that intravenous (iv) dexmedetomidine given during spinal anesthesia increases the quality of subarachnoid block (SAB). In this study, we compare the two iv regimen of dexmedetomidine on analgesic effect of spinal anesthesia. One is bolus dose of dexmedetomidine and other is infusion during the surgery, both given after induction of spinal anesthesia...

Ahmed Yousef A Al Sultan, Abdulrahman Mawadh A Alsubhi
Carotid endarterectomy (CEA) has shown a significant benefit in preventing ipsilateral stroke when it is compared to conservative management. Surgical morbidity and mortality must be kept to a minimum to achieve this benefit. Neurological status of the CEA patients can be monitored easily during regional anesthesia depending on the awake testing (neurocognitive assessment) method of the CEA patients. In addition, specific parameters can help us to monitor and to predict the neurological status of the CEA patients during the procedures such as regional cerebral oxygen saturation (rSO2 ) and middle cerebral artery velocity (MCAv) changes...

AIM: We report two cases of the very rare Primary Acquired Grynfeltt Hernia. The related abdominal wall defects were repaired, by open surgery, placing a partially absorbable plug and mesh. The observation and management of these two new cases prompted us to review the literature with the purpose of suggesting the most appropriate surgical approach and technique. MATHERIAL OF STUDY: A 60 years old female patient showing a swelling at the left lumbar region, and a 76 years old male patient showing evidence of a tumefaction located at the right lumbar region, were diagnosed at our department with Primary Acquired Grynfeltt Hernia...

BACKGROUND: Cleft lip and palate are common major congenital anomalies. Cleft palate (CP) repair causes pain and needs large doses of intravenous opioids. The risk of postoperative airway obstruction or respiratory depression is high, requiring continuous and vigilant monitoring. The primary outcome was to evaluate the efficacy of using different local anesthetics during bilateral maxillary nerve block (MNB) with general anesthesia on quality of recovery after primary CP repair. We hypothesized that levobupivacaine would be better than bupivacaine...

BACKGROUND: The beach-chair position (BCP) results in decreases in venous return, cardiac output, and cerebral perfusion pressure. In this randomized, prospective study, we investigated whether applying thigh-high compression stockings affected the maintenance of regional cerebral tissue oxygen saturation (rSO2 ) in the BCP. METHODS: Patients undergoing orthopedic surgery in the BCP under general anesthesia were included and assigned randomly to the control or the compression stocking group...

Intraosseous hemangioma is an extremely rare tumor that accounts for 1% or fewer of all osseous tumors. The most common sites of its occurrence are the vertebral column and calvaria. Occurrence in a facial bone is very rare. The authors aim to report a case of the surgical treatment of intraosseous hemangioma occurring in the periorbital region, which is a very rare site of occurrence and to introduce our own experiences with the diagnosis and treatment of this condition along with a literature review. A 73-year-old male patient visited our hospital with the chief complaint of a mass touching the left orbital rim...

Foreign body (FB) impaction in the maxillofacial area could be caused by knives, glass fragments, and vegetative materials. We present the rare case of a 62-year-old man with a large glass FB in the left cheek retained for over 40 years. He had traffic accident over 40 years ago and glass fragments impacted on his left cheek. Glass fragments were retained around the zygomatic arch with dimpled scar and unclear serous discharge, but other facial motor or sensory dysfunction was not observed. We confirmed three glass fragments with radiologic examination including plain radiograph and computed tomographic image...
