We read with great interest the article of Wang et al.1 concerning the use of continuous local anesthetic infusion via catheters placed with ultrasound guided and nerve stimulator beside femoral nerve for postoperative analgesia after total knee arthroplasty (TKA). We congratulate them on the presentation of the article. However, we would like to add some comments. We agree with author that reh...

provided the original work is properly cited. CC After total knee arthroplasty (TKA), patients suffer pain; therefore, many analgesic techniques have been invented. Epidural analgesia is widely used and can be delivered by continuous epidural infusion (CEI), patient controlled epidural analgesia (PCEA), or intermittent epidural bolus (IEB). However, CEI is associated with greater incidence of m...

Pain during labor and delivery is often very unpleasant and stressful for the parturients. Patient controlled epidural analgesia (PCEA) has been found to be both safe and effective, providing optimal pain relief and allowing women to participate in their own analgesia). Compared to other epidural techniques, intermittent epidural top-ups and continuous epidural analgesia (CEA), PCEA uses dilute...

BACKGROUND Low-dose combined spinal-epidural analgesia in labor has proved popular with women because lower-limb motor power is preserved, allowing ambulation. However, there has been debate about the safety of allowing women to walk following low-dose regional analgesia because of somatosensory impairment. The authors undertook a prospective controlled observational study using computerized dy...

We report the failure of a test dose of 3 ml lidocaine 1.5 per cent with 15 micrograms epinephrine to identify subdural placement of an epidural catheter in a parturient. Thirty-five minutes after injection of 13 ml lidocaine 1.5 per cent, intended to provide epidural analgesia, the patient developed an extensive sensory neural blockade. Some motor control was maintained and sympathetic block w...

Several strategies and alternative therapies have been used to provide analgesia for labour pain. Over the last few years, a number of improvements have enhanced the efficacy and safety of neuraxial analgesia and ultimately have improved mothers' satisfaction with their birth experience. As labour analgesia is a field of obstetric anaesthesia that is rapidly evolving, this review is an update, ...
