Anatomical classification and clinical application of thoracic paraspinal blocks

Shin Hyung Kim

Korean J Anesthesiol. 2022;75(4):295-306.

Various techniques for regional anesthesia and analgesia of the thorax are currently being used in clinical practice. A recent international consensus has anatomically classified paraspinal blocks in the thoracic spinal region into the following four types: paravertebral, retrolaminar, erector spinae plane, and intertransverse process blocks. These blocks have different anatomical targets; thus, the spreading patterns of the injectates differ and can consequently exhibit different neural blockade characteristics. The paravertebral block directly targets the paravertebral space just outside the neuraxial region and has an analgesic efficacy comparable to that of the epidural block; however, there are multiple potential risks associated with this technique. Retrolaminar and erector spinae plane blocks target the...

Remimazolam – current knowledge on a new intravenous benzodiazepine anesthetic agent

Seong-Hyop Kim, Jörg Fechner

Korean J Anesthesiol. 2022;75(4):307-315.

Intravenous anesthetic agents such as midazolam, propofol, and ketamine are routinely used to provide anesthesia and sedation. They have been shown to effectively induce and maintain amnesia, sedation, and hypnosis in various patient groups and clinical settings. However, all anesthetic agents have the potential to cause unwanted side effects such as hemodynamic instability, respiratory depression, or slow recovery due to prolonged post-procedural sedation. Remimazolam, a recently approved benzodiazepine for general anesthesia and procedural sedation in Korea, has been successfully used for these purposes. To date, inconclusive knowledge has been obtained regarding the use of remimazolam in different patient populations and under various surgical conditions. With respect to the specific pharmacokinetic...

Comparison of the clinical performance of the i-gel^TM, LMA Supreme^TM, and Ambu AuraGain^TM in adult patients during general anesthesia: a prospective and randomized study

Tejashri Chinthavali Lakshmi, Tanmay Tiwari, Jyotsna Agrawal, Rajni Kapoor, Vikrannth Vasanthakumar

Korean J Anesthesiol. 2022;75(4):316-322.

Background: Supraglottic airway devices (SADs) are routinely used for securing the airway. In this study, the clinical performance of three SADs in adult patients under general anesthesia was compared. Methods: American Society of Anesthesiologists physical status I-III subjects were randomly assigned to the i-gelTM (I), LMA SupremeTM (L), or Ambu AuraGainTM (A) group (30 per group). The primary objective of this study was to compare insertion times. Additionally, the ease of insertion, number of attempts, oropharyngeal leak pressure (OLP), airway maneuver requirement, difficulty with gastric tube placement, and complications were assessed. Results:...

Comparison between the coronal diameters of the cervical spinal canal and spinal cord measured using computed tomography and magnetic resonance imaging in Korean patients

So Young Lee, In Young Kim, Kyung Wook Jeong, Taeha Ryu, Sang Kyu Kwak, et al.

Korean J Anesthesiol. 2022;75(4):323-330.

Background: If the proportion of the spinal cord in the epidural space can be determined under C-arm fluoroscopy during cervical epidural block, a safe entry point for the epidural needle can be established. The aim of this study was the measurement of the cord to canal transverse diameter ratio of each cervical spines. Methods: We retrospectively evaluated the imaging data of 100 patients who underwent both cervical computed tomography (CT) and cervical magnetic resonance imaging (MRI) at our hospital. We measured the diameters of the spinal canal and spinal cord...

Video laryngoscope versus USB borescope-aided endotracheal intubation in adults with anticipated difficult airway: a prospective randomized controlled study

Mohamed Elshazly, Mark Medhat, Sahar Marzouk, Enas M. Samir

Korean J Anesthesiol. 2022;75(4):331-337.

Background: Video laryngoscopes are approved equipment for difficult airway intubations. The borescope, which was introduced during the coronavirus disease 2019 (COVID-19) era, is placed over a direct laryngoscope blade to provide an economical video laryngoscope. In the current study, we investigated the use of an endotracheal tube mounted over a USB borescope versus a video laryngoscope in patients with suspected difficult airways. Methods: After obtaining informed consent, 120 adult patients with suspected difficult airways undergoing elective surgery were included in this study. Patients were randomized into the USB borescope and video...

Microvascular reactivity as a predictor of major adverse events in patients with on-pump cardiac surgery

Ah-Reum Cho, Hyeon-Jeong Lee, Jeong-Min Hong, Christine Kang, Hyae-Jin Kim, et al.

Korean J Anesthesiol. 2022;75(4):338-349.

Background: Microcirculatory disturbances are typically most severe during cardiopulmonary bypass (CPB), which occurs during cardiac surgeries. If microvascular reactivity compensates for microcirculatory disturbances during CPB, tissue hypoxemia can be minimized. The primary aim of this study was to assess whether microvascular reactivity during CPB could predict major adverse events (MAE) after cardiac surgery. Methods: This prospective observational study included 115 patients who underwent elective on-pump cardiac surgeries. A vascular occlusion test (VOT) with near-infrared spectroscopy was performed five times for each patient: before the induction of general anesthesia, 30 min after the induction of general anesthesia, 30 min after applying CPB, 10 min after protamine injection, and post-sternal closure. The postoperative...
