Systemic Lidocaine Infusion for Post-Operative Analgesia in Children Undergoing Laparoscopic Inguinal Hernia Repair: A Randomized Double-Blind Controlled Trial.

Systemic lidocaine can provide satisfactory post-operative analgesia in adults. In this study, we assessed whether intravenous lidocaine is effective for post-operative analgesia and recovery in children undergoing laparoscopic inguinal hernia repair. A total of 66 children aged from six months to less than six years were classified in either the lidocaine (L) or control (C) groups.

Effects of Positive End-Expiratory Pressure on Pulmonary Oxygenation and Biventricular Function during One-Lung Ventilation: A Randomized Crossover Study.

Although the application of positive end-expiratory pressure (PEEP) can alter cardiopulmonary physiology during one-lung ventilation (OLV), these changes have not been clearly elucidated. This study assessed the effects of different levels of PEEP on biventricular function, as well as pulmonary oxygenation during OLV. Thirty-six lung cancer patients received one PEEP combination of six sequences, consisting of 0 (PEEP_0), 5 (PEEP_5), and 10 cmHO (PEEP_10), using a crossover design during OLV.

The Effects of Intravenous Lidocaine Infusions on the Quality of Recovery and Chronic Pain After Robotic Thyroidectomy: A Randomized, Double-Blinded, Controlled Study.

Background: The effect of the systemic lidocaine on postoperative recovery has not been definitively investigated despite its analgesic efficacy after surgery. The aim of this randomized, double-blinded, controlled study was to evaluate the effect of intravenously administered lidocaine on the quality of recovery and on acute and chronic postoperative pain after robot-assisted thyroidectomy.

Methods: Ninety patients who were undergoing robotic thyroidectomy were randomly assigned to the lidocaine or the control groups.

Determination of EC95 of remifentanil for smooth emergence from propofol anesthesia in patients undergoing transsphenoidal surgery.

Background: In patients undergoing pituitary surgery using a transsphenoidal approach, anesthesia emergence should be smooth with minimal coughing. Recent studies demonstrated that a target-controlled infusion of remifentanil effectively suppresses coughing induced by the endotracheal tube. We investigated the EC95 of remifentanil for smooth emergence without coughing from propofol anesthesia in patients undergoing transsphenoidal hypophysectomy.

The randomized crossover comparison of airway sealing with the laryngeal mask airway Supreme(™) at three different intracuff pressures in children.

Background: An intracuff pressure of 80 cm H2 O in the adult-sized laryngeal mask airway Supreme has been recommended to obtain a higher oropharyngeal leak pressure (OLP). However, the intracuff pressure for the higher OLP in the pediatric laryngeal mask airway Supreme could be different from that in the adult-sized laryngeal mask airway Supreme. Thus, we measured and compared OLP at three intracuff pressures of 40, 60, and 80 cm H2 O in the pediatric laryngeal mask airway Supreme.

High-dose daily opioid administration and poor functional status intensify local anesthetic injection pain in cancer patients.

Background: Evidence for opioid-induced hyperalgesia (OIH) has been shown in animal and human studies, but the clinical implications of this phenomenon remain unclear.

Objectives: We examined whether cancer patients taking opioids differ in their sensitivity to a clinical pain stimulus using a local anesthetic injection compared to those not taking opioids. We also evaluated the effect of the opioid dose, duration of opioid therapy, and patients' pain severity and functional status on this clinical pain stimulus.

Popliteal Fossa Pain in 24 Year-old Female.

The pain around the posterior knee, called 'popliteal fossa', has been known to be caused by a variety of disease entities. Venous malformation is a very rare cause of popliteal area pain, and its diagnosis is frequently delayed, missed, or given incorrectly. Here, we report a case of a patient with popliteal fossa pain for 2 years and was diagnosed as intramuscular venous malformation using ultrasound.

The effect of electrically heated humidifier on the body temperature and blood loss in spinal surgery under general anesthesia.

Background: General anesthesia often produces some degree of hypothermia and hypothermia causes much more blood loss during surgery than normothermia. Electrically heated humidifiers (EHHs) have been used for patients under general anesthesia and in the intensive care unit. However, the benefits of the EHH have not been widely reported in the literature.
