Detection of paradoxical carbon dioxide gas embolism with opening of patent foramen ovale by perioperative transesophageal echocardiography during laparoscopic hepatectomy - A case report.

Background: Due to its various advantages, laparoscopic surgery is preferred over laparotomy in patients who require hepatic resection. Carbon dioxide embolism -which occurs approximately ten times more often in laparoscopic hepatectomy than in general laparoscopic surgery-presents with insignificant symptoms and may be overlooked.

Case: A 70-year-old male with hepatic cell carcinoma underwent laparoscopic hepatectomy.

The experience of infection prevention for coronavirus disease 2019 (COVID-19) during general anesthesia in an epidemic of COVID-19: including unexpected exposure case - Two cases report.

Background: Coronavirus disease 2019 (COVID-19) has been an epidemic in the Republic of Korea since the first patient who came in China was confirmed as having the disease on January 19, 2020. Therefore, surgery for COVID-19-related patients is expected to increase.

Case: We experienced two cases of COVID-19-related patients who underwent surgery for femur fracture under general anesthesia.

Polydeoxyribonucleotide injection in the treatment of patients with carpal tunnel syndrome: Retrospective preliminary study.

Background: Corticosteroid injection is beneficial in treating carpal tunnel syndrome (CTS) due to its anti-inflammatory effects. However, its side effects limit widespread usage. Recently, several studies have found that polydeoxyribonucleotide offers anti-inflammatory capabilities with fewer side effects, making it an ideal alternative.

Intramuscular hematoma with motor weakness after trigger point injection: A case report.

Rationale: Although trigger point injection is known as an easy and low-risk procedure, it is contraindicated to patients with hemorrhagic disorders or who regularly take anticoagulants/antiplatelets. However, taking clopidogrel is not a defined contraindication to this low-risk procedure.

Patient Concerns: The chief complaint of a 76-year old woman regularly taking clopidogrel was low back and left buttock pain which prolonged for several years.

Severe desaturation while attempting one-lung ventilation for congenital cystic adenomatoid malformation with respiratory distress syndrome in neonate -A case report-.

There are many methods for achieving one-lung ventilation (OLV) during thoracic surgery in neonates and the accuracy of OLV may affect postoperative outcome. The authors have performed OLV using a 5 Fr Arndt endobronchial blocker (AEB, Cook Inc., Bloomington, IN, USA) on a neonate diagnosed with congenital cystic adenomatoid malformation and respiratory distress syndrome (RDS) associated with marked mediastinal shift.

Successful tracheal intubation using fiberoptic bronchoscope via an I-gel™ supraglottic airway in a pediatric patient with Goldenhar syndrome -A case report-.

The I-gel™ is a single-use supraglottic airway device introduced in 2007 which features a non-inflatable cuff and allows passage of a tracheal tube owing to its large diameter and short length of the airway tube. In this case, the authors experienced a difficult airway management on a 4-year-old boy with underlying Goldenhar syndrome who underwent a tonsillectomy. Intubation using a laryngoscope was unsuccessful at the first attempt.
