Progressive paraplegia after upper thoracic epidural block-related pneumorachis: A case report.

INTRODUCTION AND IMPORTANCE: While the typical symptom associated with pneumorachis after an epidural block is radiculopathy in one or several corresponding segments, there has been a rare case report of significant complications such as cardiac arrest leading to death, or paraplegia. CASE PRESENTATION: We present a case of an eighty-nine-year-old male patient who developed progressive paraplegia following an upper thoracic epidural block-associated pneumorachis. The procedure was performed at a different hospital using the loss of resistance (LOR) technique. Interestingly, the onset of paraplegia was delayed, occurring six hours after the procedure. Furthermore, there was a discrepancy between the clinical symptoms and the identified lesion in imaging studies. Despite the performance of an emergency laminectomy to remove the epidural gas, the paralysis continued to progress proximally. CLINICAL DISCUSSION: Healthcare professionals should observe patients for an appropriate duration after the procedure to detect and manage any delayed symptoms. And it is crucial to recognize the potential for lesion extension beyond the symptomatic segment and perform thorough imaging examinations. CONCLUSION: These findings emphasize the importance of exercising caution during the procedure, even when using a minimal amount of air with the LOR technique in the thoracic spine.

A fiberoptic orotracheal intubation successfully performed using a modified Guedel airway in a sedated emergency patient - A case report.

BACKGROUND: Fiberoptic intubation is a powerful and safe technique to deal with airway difficulty, but it requires a lot of training to be able to perform correctly. There are various specialized oral airways for fiberoptic intubation, but none of them have perfect functionality. CASE: A 75-year-old male (body weight 71.6 kg, height 159.3 cm, body mass index 28.22 kg/m2) was diagnosed with acute appendicitis, and it was decided to do a laparoscopic appendectomy. After the induction of general anesthesia, it was impossible to insert the direct laryngoscope deep enough for vocal cord visualization without damaging the teeth because of limited mouth opening. We successfully performed fiberoptic intubation with a newly modified Guedel airway via a longitudinal channel on the convex side and a distal opened lingual end. CONCLUSIONS: Our modified Guedel airway can be useful in assisting fiberoptic intubation in unexpectedly difficult airway situations.

Treatment of digit ulcers in a patient with Buerger's disease by using cervical spinal cord stimulation -a case report-.

Buerger's disease (thromboangiitis obliterans) is known as a segmental inflammatory vasculitis that involves the small-sized and medium-sized arteries, veins, and nerves. Most effective treatment for Buerger's disease is smoking cessation. Except for the cessation of tobacco use, surgical revascularization is available in severe ischemia and a distal target vessel. Amputation has been used as the last treatment option of the disease up to the present. Increasing limb survival and decreasing amputation rate is important. This case describes the use of spinal cord stimulation (SCS) in patient with Buerger's disease and its effect is not only the complete healing of ulcers but also amputation is not performed.

Effect of pretreatment with gabapentin on withdrawal movement associated with intravenous rocuronium injection.

BACKGROUND: The major disadvantage of rocuronium is the withdrawal movement associated with its injection. The analgesic effect of perioperative gabapentin has been evaluated. We investigated the effects of gabapentin on the withdrawal movement induced by rocuronium injection. METHODS: 86 ASA physical status I or II patients, aged 18-69 years who were scheduled to undergo elective surgery with general anesthesia were enrolled. Patients were randomly allocated into two groups to receive either gabapentin 600 mg or placebo 2 hours prior to surgery. The patient's response to rocuronium injection was graded using a 4-point scale. RESULTS: The incidence of withdrawal movement after rocuronium administration was significantly lower in the gabapentin group (55.0% in the control group vs 28.6% in the gabapentin group). The number of patients with generalized response indicating severe pain, was 9 (22.5%) in the control group and 3 (7.1%) in the gabapentin group. CONCLUSIONS: Pretreatment with a single oral dose of gabapentin 600 mg reduced the incidence and severity of withdrawal movement after rocuronium administration.

Anesthetic experience of methemoglobinemia detected during general anesthesia for gastrectomy of advanced gastric cancer -A case report-.

Methemoglobinemia is an uncommon but potentially fatal disorder. Most cases have no adverse clinical consequence and require no treatment, but methemoglobinemia is often overlooked as a cause of low oxygen saturation, and often mistaken for the more common causes of hypoxia by anesthesiologists despite simple bedside tests that indicate the presence of this treatable abnormality. We present a 68-year-old female patient who underwent gastrectomy for advanced gastric cancer with bleeding. In the preoperative period, the patient showed cyanosis and oxygen saturation was 85% by pulse oximeter, but oxygen saturation by arterial blood gas analysis was 100%. After tracheal intubation, the methemoglobin level was 18.3%. Ascorbic acid and methylene blue were administered. During preanesthetic evaluation, the patient had not informed the anesthesiologist that she had been taking dapsone.

Airway obstruction by extrinsic tracheal compression during spinal surgery under prone position -A case report-.

Tracheal compression by vascular anomalies in adults is uncommon and most related reports are of children. A 79-year-old woman without any respiratory history underwent a lumbar spine surgery under general anesthesia. She suddenly developed airway obstruction after a position change from supine to prone. A fiberoptic bronchoscopy showed the obstruction of endotracheal tube. The obstruction was relieved after we changed the depth of endotracheal tube and supported the patient's neck with a cotton roll. The surgery ended without any other event and the patient recovered safely. A computed tomography revealed the rightward tracheal deviation and tortuous innominate artery contact with trachea. The patient didn't manifest any respiratory related symptoms during postoperative period, and she was discharged without any treatment.

Suspicious stress induced cardiomyopathy following hemorrhoidectomy under spinal anesthesia: A case report.

A 48-year-old healthy woman was admitted in our hospital for elective hemorrhoidectomy. She developed sudden headache and chest pain, and showed sinus bradycardia, arrhythmia and hypotension forty minutes after spinal anesthesia with 0.5% hyperbaric bupivacaine. An EKG showed ST depression and an transthoracic echocardiogram performed in PACU demonstrated mild LV dysfunction with hypokinesia of LV inferolateral wall. An coronary angiography on postoperative day 1 revealed normal coronary vessel and akinesia of LV inferior wall. Levels of CK-MB and Troponin I were mildly elevated. With medical therapy, the patient's symptoms improved and recovered without any complication.
