The efficacy and safety of combined pulsed and conventional radiofrequency treatment of refractory cases of idiopathic trigeminal neuralgia: a retrospective study.
We conducted a retrospective study to evaluate the efficacy and duration of pain relief for idiopathic trigeminal neuralgia (TN) patients after continuous radiofrequency (CRF) combined with pulsed radiofrequency (PRF) treatment of the Gasserian ganglion (GG). ⋯ Excellent pain relief and reduced consumption of analgesics for more than 6 months were observed in patients who received PRF combined with CRF to the GG for treatment of idiopathic TN.

Randomized Controlled TrialEffect of mini-dose epidural dexmedetomidine in elective cesarean section using combined spinal-epidural anesthesia: a randomized double-blinded controlled study.
Combined spinal-epidural anesthesia is commonly used for elective cesarean section. Our study aimed to evaluate the effect of adding dexmedetomidine to epidural bupivacaine and fentanyl in patients undergoing elective cesarean section using combined spinal-epidural anesthesia. ⋯ The addition of mini-dose epidural dexmedetomidine 0.5 µg/kg as a single injection to bupivacaine fentanyl in women undergoing elective cesarean section with combined spinal-epidural anesthesia improved intraoperative conditions and the quality of postoperative analgesia.

ReviewHistory of T-cain: a local anesthetic developed and manufactured in Japan.
In many anesthesia textbooks written in English, lidocaine, tetracaine, bupivacaine, ropivacaine, and chloroprocaine are listed as useful local anesthetics for spinal anesthesia. In contrast, T-cain is not included in these lists, even though it has been reported to be suitable for spinal anesthesia in Japan. T-cain was developed as a local anesthetic in the early 1940s by Teikoku Kagaku Sangyo Inc. in Itami, Japan, by replacing a methyl group on tetracaine (Pantocaine(®)) with an ethyl group. ⋯ Other than the side effects generally known for all local anesthetics, serious side effects have not been reported for T-cain. In fact, several articles have reported that T-cain decreases the neurotoxicity of dibucaine. In this historical review, the characteristics of T-cain and its rise to become a major spinal anesthetic in Japan are discussed.

Estimation of catheter insertion depth during ultrasound-guided subclavian venous catheterization.
Several methods have been used to predict the optimal depth of central venous catheter (CVC) tip position when using the anatomical landmark technique. In the present study, we devised a simple formula to predict CVC depth using ultrasound images and chest X-ray (CXR) in patients undergoing ultrasound-guided subclavian venous catheterization. ⋯ The appropriate length of a CVC inserted through the subclavian vein can be estimated by a formula using ultrasound images and CXR.
