Delayed Extubation of a Patient With Multiple Sclerosis.

The potential complications associated with gastroparesis in the perioperative setting for patients with multiple sclerosis (MS) are inadequately recognized. While gastroparesis is commonly associated with diabetes mellitus-induced neuropathy and postsurgical complications, its prevalence and impact on patients with MS are less understood. This is particularly crucial as the systemic autoimmune nature of MS may extend its neurological effects to the gastrointestinal (GI) tract.

Laparoscopic Extended Left Lateral Sectionectomy for Hepatocellular Carcinoma in a Patient with Right-Sided Ligamentum Teres: A Case Report and Literature Review.

Right-sided ligamentum teres (RSLT) is a rare anatomic variant in which the fetal umbilical vein connects to the right portal vein. Patients with RSLT frequently have hepatic vasculature and bile duct anomalies, which increase the risk of complications with hepatectomy. Most patients with RSLT undergo open hepatectomy.

Ideal endotracheal intubation depth at the vocal-cord level to avoid single-lung intubation using the percentage ratio of the tracheal length to body height.

Introduction: Our previous study revealed racial differences in the tracheal length of cardiac paediatric patients between Germany and Japan. The current study was conducted in two stages, aiming to determine whether the tracheal length differs between cardiac and non-cardiac paediatric patients and whether the results could also be generalised to adults.

Material And Methods: The first stage was a retrospective observational evaluation of 335 cardiac and 275 non-cardiac paediatric patients in Japan.

Regional anesthesia as part of enhanced recovery strategies in pediatric cardiac surgery.

Purpose Of Review: The purpose of this review article was to highlight the enhanced recovery protocols in pediatric cardiac surgery, including early extubation, rapid mobilization and recovery, reduction of opioid-related side effects, and length of pediatric ICU and hospital stay, resulting in decreased costs and perioperative morbidity, by introducing recent trends in perioperative anesthesia management combined with peripheral nerve blocks.

Recent Findings: Efficient postoperative pain relief is essential for realizing enhanced recovery strategies, especially in pediatric patients. It has been reported that approaches to perioperative pain management using additional peripheral nerve blocks ensure early extubation and a shorter duration of ICU and hospital stay.

Lymphoepithelioma-like cholangiocarcinoma not associated with Epstein-Barr virus or hepatitis virus: case report and literature review of 100 reported cases.

Lymphoepithelioma-like cholangiocarcinoma (LEL-CC) is a type of lymphoepithelioma-like carcinoma (LELC) and a rare variant of primary liver tumor. Although it is uncommon and only 100 cases have been reported thus far, the number of reports has increased in recent years. LEL-CC reportedly occurs more frequently in Asian women; Epstein-Barr virus (EBV) and hepatitis viruses are both strongly associated with tumor development.

Femoral Artery Cannulation Timing for a Pediatric Aortic Arch Repair.

We have previously introduced a blood delivery method via femoral artery cannulation to provide perfusion to the organs in the lower part of the body during pediatric aortic arch repair surgeries. In the original procedure, the femoral artery cannulation was performed after the patient had been covered with a sterile drape. Here, we suggest that the femoral artery cannulation should be performed before the patient is draped to allow optimal visibility of the target artery and puncture needle via aseptic real-time ultrasound-guided technique by reducing the inclusions between the patient's skin and ultrasound probe which attenuate the ultrasound beam.

Unexpected difficult airway due to an undiagnosed congenital lingual thyroglossal duct cyst in a neonate without stridor: A case report.

Lingual thyroglossal duct cysts can be a rare cause of feeding difficulties in infants. Here, we describe a case of an infant with vomiting and feeding difficulty diagnosed with Hirschsprung's disease. However, she developed an unexpected difficult airway during anesthesia induction due to an undiagnosed lingual thyroglossal duct cyst.

Paradoxical Platypnea-Orthodeoxia Syndrome Induced by Patent Foramen Ovale and Highly Tortuous Descending Thoracic Aorta: A Case Report.

Perioperative hypoxemia is common in patients with aortic dissection. Platypnea-orthodeoxia syndrome (POS), in which hypoxemia in the upright position improves with relocating to a recumbent position, can be a rare cause of hypoxemia. This syndrome is more likely to occur in patients with an intracardiac shunt and aortic malformation.

Ensure an "Ultrasound Window" on the Patient's Neck to Evaluate Cerebral Blood Flow!

Near-infrared spectroscopy (NIRS) does not provide information about changes in oxygenation in whole-brain areas. Although the branching vessels of the aortic arch are not always easy to identify using transesophageal echocardiography (TEE), the blood flow status of cervical arteries can always be assessed by applying an ultrasound probe via the "ultrasound window" on the patient's neck, which can be ensured by devising alternative insertion approaches of the central venous catheter. This method is very simple but compensates for the limitations of the combination of NIRS and TEE, especially during cardiac surgery with cardiopulmonary bypass management using selective cerebral perfusion.

A real-time ultrasound-guided supraclavicular approach to the brachiocephalic vein to prevent Hickman catheter bending and occlusion.

The infraclavicular approach (subclavian approach) to the central vein is most often selected for implantation of a tunnelled Hickman/Broviac cathe­ter because central venous catheter (CVC) insertion into the upper body is optimal considering patient comfort as well as the risk of infection [1] and intravenous thrombosis [2, 3]. How­ever, the actual puncture site for a real-time ultrasound-guided infraclavicular axillary vein approach is at the level of the axillary vein in a much more lateral location than that for the traditional landmark infraclavicular approach to the subclavian vein. This is because an optimal view of the subclavian vein is difficult to obtain with a real-time ultrasound-guided technique, as the ultrasound beam is restricted by the clavicle [4]; the younger the patient, the greater would be its influence because of the width of the ultrasound probe.

Precaution: Oximetry central venous catheter shaft is no longer waterproof when cut.

his letter discusses precautions regarding the waterproof structure of the oximetry central venous catheter (CVC) shaft and the risk of blood reflux and leakage that can occur when the catheter shaft is cut. To assess oxygen supply-demand balance [1] and haemodynamics [2], the Swan-Ganz pulmonary artery catheter has been used for perioperative and postoperative management and treatment of critically ill patients for a half a century. In current clinical practice, haemodynamic parameters such as stroke volume (SV) and cardiac output (CO), as well as central venous oxygen saturation (ScvO2), can be measured continuously using a combination of FloTrac Sensor (Edwards Lifesciences Japan Ltd.

Novel Choices of Cannula for Blood Delivery via Femoral Artery in Pediatric Patients.

We previously presented a cardiopulmonary bypass (CPB) method with blood delivery via femoral artery cannulation for pediatric aortic arch repair operations using the Radifocus Introducer sheath. However, the flow rate with the Radifocus Introducer sheath is limited by accessory parts with the same structure having a smaller inner diameter among different sizes, rather than the sheath body. Therefore, we further devised a combination of the JELCO IV catheter, an extension tube, and a three-way stopcock with a larger opening to obtain more flow rate keeping the CPB circuit pressure significantly lower than when using the Radifocus Introducer sheath successfully.

Preoperative Implementation of Transverse Thoracic Muscle Plane Block and Rectus Sheath Block Combination for Pediatric Cardiac Surgery.

Systemic intravenous administration of opioids is the main treatment strategy for intraoperative and postoperative pain management in patients undergoing cardiac surgery with sternotomy. However, using lower doses of opioids may achieve the well-established benefits of the fast-track approach, with minimal opioid-related side effects. Postoperative pain is coupled with a long stay in the intensive care unit.

Congenital Tracheal Aplasia Without Prenatal Diagnosis Masked by Maternal Obesity and Gestational Diabetes: A Case Report.

This case report describes a neonate with tracheal aplasia first diagnosed after birth due to the presentation of respiratory distress, absence of crying, and unsuccessful tracheal intubation. The most common finding with tracheal aplasia is polyhydramnios. However, diagnosis remains challenging in the prenatal period.
