Evaluation of ultrasound-guided posterior quadratus lumborum block for postoperative analgesia after laparoscopic gynecologic surgery.

Study Objective: This study aimed to determine the efficacy of ultrasound-guided posterior quadratus lumborum block (QLB) in treating postoperative pain following laparoscopic gynecologic surgery.

Design: Prospective randomized controlled study.

Patients: Seventy adult patients scheduled for elective laparoscopic gynaecological surgery under general anesthesia.

Contribution of the nasal passage to face mask ventilation: a prospective blinded randomized crossover trial.

Background: Previous studies have shown that the nasal passage plays an important role in manual face mask ventilation, but this has yet to be quantitatively assessed. We conducted a prospective randomized crossover clinical trial to compare the change in pressure-controlled face mask tidal volume with and without nasal airway occlusion.

Method: Female patients undergoing elective surgery under general anesthesia served as study subjects.

[Efficacy of Go-rei-san for Pain Management in Four Patients with Intractable Trigeminal Neuralgia].

Go-rei-san is a Japanese traditional medicine that is used to treat motion sickness, nausea, and vomiting. We report here four patients for whom Go-rei-san was effective in treating pain associated with intractable trigeminal neuralgia. Three patients could not continue carbamazepine due to drug-induced rash, liver damage, and gastrointestinal injury, and suffered from pain.

[Efficacy of Transversus Abdominis and Rectus Sheath Blocks in Combination with Continuous Intravenous Fentanyl for Postoperative Analgesia of Laparoscopic Colectomy: A Retrospective Study].

Background: Ultrasound-guided transversus ab- dominis plane (TAP) and rectus sheath (RS) blocks are peripheral nerve blocks that diminish somatic pain of the abdominal wall and are useful for postoperative analgesia. Here, we retrospectively compared the effi- cacy of ultrasound-guided TAP and RS blocks in com- bination with continuous intravenous fentanyl for postoperative analgesia of laparoscopic colectomy.

Methods: The ethics committee of our institute ap- proved the study.

Impact of pillow height on double-lumen endotracheal tube intubation with McGRATH MAC: a prospective randomized clinical trial.

Study Objective: This study aimed to compare the impact of pillow height on double-lumen tracheal tube (DLT) intubation with McGRATH MAC (McG) in patients undergoing elective surgery.

Design: Randomized clinical trial.

Setting: Operating room.

LMA-ProSeal insertion by novice doctors as affected by a 90° bend created by an intubating stylet: a randomized clinical trial.

Study Objective: This study aimed to test the hypothesis that insertion of the supraglottic device LMA-ProSeal (ProSeal) by novice doctors in anesthetized patients can be improved by using an intubating stylet to create a 90° bend and that better sealing pressure is achieved.

Design: Randomized clinical trial.

Setting: Operating room.

[Ultrasound-guided Thoracic Epidural and Spinal Anesthesia for the Management of Patients Undergoing Systemic Neurofibroma Resection].

We report successful anesthetic management of a patient undergoing systemic neurofibroma resection using thoracic epidural and spinal anesthesia. A 40- year-old man (weight 66 kg) with von Recklinghausen's disease and intermittent convulsions was scheduled for large-scale tumor resection on the back and arms. He also had chronic obstructive pulmonary disease and stiff neck We decided not to perform operation under general anesthesia.

Muscle relaxant facilitates i-gel insertion by novice doctors: A prospective randomized controlled trial.

Study Objective: This study aimed to determine whether muscle relaxants facilitates insertion efficacy of the i-gel supraglottic device (i-gel) by novice doctors in anesthetized patients.

Design: Randomized clinical trial.

Setting: Operating room.

Comparison of polyvinyl chloride and elastic stannum stylet extraction forces with various lubricants: a simulation study.

Background: Stylets are the most frequently used devices for tracheal intubation, but can be a source of postoperative pharyngeal pain or hoarseness. In this study, we evaluated extraction forces between polyvinyl chloride (PVC) and stannum (Sn) stylets with various lubricants.

Findings: Using a manikin, we compared extraction forces between PVC and Sn stylets under four different conditions: without lubricant, 3 ml of water (water), three sprays of 8 % lidocaine (lidocaine), and olive oil.

[Anesthetic Management of Peritonectomy and Extended Operation for Peritoneal Pseudomyxoma Combined with Massive Ascites].

We report successful anesthetic management of extended operation for peritoneal pseudomyxoma combined with massive ascites (16.5 l). A 66-year-old man (weight 76 kg) who could not keep a supine position due to massive ascites associated with peritoneal pseudomyxoma was scheduled for elective peritonectomy and extended surgery.

[Effective Dexmedetomidine Administration for the Prevention of Emergence Agitation and Postoperative Delirium in Patients with a History of Postoperative Delirium].

We successfully performed intraoperative dexmedetomidine (DEX) administration for the prevention of emergence agitation or postoperative delirium after lung resection in four patients (71.3 ± 5.7 year old, 3 males and 1 female) with a past history of postoperative delirium.

[Anesthetic Management of Video-assisted Left Upper Lobectomy in a Patient with Ischemic Heart Disease Using an Intraaortic Balloon Pump].

We report the successful anesthetic management of video-assisted left upper lobectomy in a patient with ischemic heart disease using an intra-aortic balloon pump (IABP). An 81-year-old man with severe ischemic heart disease was scheduled for partial lobectomy for suspected lung cancer under general anesthesia. Although he had severe ischemic heart disease, coronary intervention such as percutaneous cardiac intervention or coronary artery bypass grafting was impossible due to severe coronary stenosis.

[Anesthetic Management for Lobectomy in a Patient with Pulmonary Arterial Hypertension].

Pulmonary arterial hypertension (PAH) is a known risk factor of perioperative complications, but the risks for non-cardiac operations have not yet been examined sufficiently. We report a case of a right lower lobectomy in a patient with PAH. A 73-year-old woman with Sjögren's syndrome was scheduled for right lowr lobectomy for primary lung cancer under general anesthesia.

Evaluation of double-lumen endotracheal tube extubation force by extraction angle: a prospective randomized clinical trial.

Study Objective: Gentle and noninvasive double-lumen tracheal tube (DLT) extubation is important for both airway and circulatory management, especially after lung resection. We performed a prospective randomized clinical trial comparing DLT extubation force based on 2 different extraction angles.

Design: Randomized clinical trial.

[Successful Resuscitation from Cardiac Arrest due to Pulmonary Artery Rupture Utilizing Cardiopulmonary Bypass].

We report a case of successful resuscitation from cardiac arrest due to pulmonary artery rupture utilizing cardiopulmonary bypass. A 79-year-old man was diagnosed with lung cancer; segment resection of the upper lung was scheduled under general anesthesia. Anesthesia was induced uneventfully and surgery began in the right lateral position.
