Randomized Controlled TrialAdductor canal blockade for moderate to severe pain after arthroscopic knee surgery: a randomized controlled trial.
The analgesic effect of the adductor canal block (ACB) after knee surgery has been evaluated in a number of trials. We hypothesized that the ACB would provide substantial pain relief to patients responding with moderate to severe pain after arthroscopic knee surgery. ⋯ The ACB is a relevant option for patients with moderate to severe pain after arthroscopic knee surgery.

Clinical TrialDehydration and fluid volume kinetics before major open abdominal surgery.
Assessment of dehydration in the preoperative setting is of potential clinical value. The present study uses urine analysis and plasma volume kinetics, which have both been validated against induced changes in body water in volunteers, to study the incidence and severity of dehydration before open abdominal surgery begins. ⋯ The degree of dehydration before major surgery was modest as evidenced both by urine sampling and volume kinetic analysis.

Lower incidence of post-dural puncture headache with spinal catheterization after accidental dural puncture in obstetric patients.
Accidental dural puncture (ADP) and post-dural puncture headache (PDPH) are important complications of obstetric regional anesthesia. Inserting the catheter intrathecally after ADP to prevent PDPH has gained popularity. Nonetheless, data on the effect of an intrathecal catheter on PDPH and epidural blood patch (EBP) rates are mixed. Our primary objective was to examine if spinal catheterization reduces the incidence of PDPH after ADP in obstetric patients. ⋯ The incidence of ADP, PDPH and blood patching is similar with previously published studies. After witnessed ADP, inserting the epidural catheter intrathecally significantly reduced the incidence of PDPH.

Case ReportsMeralgia paresthetica-like symptoms following epidural analgesia after total knee arthroplasty.
Meralgia paresthetica (MP) is generally caused by entrapment of the lateral femoral cutaneous nerve (LFCN), and presents with pain and paresthesia in the anterolateral thigh. This paper describes a patient who had MP-like symptoms as a result of continuous epidural analgesia after total knee arthroplasty. The patient with pre-existing left foraminal stenosis at L3-L4 and disc herniations at L4-5 did not complain of paresthesia or pain during the combined spinal-epidural anesthetic procedure. ⋯ Although an ultrasound-guided diagnostic block of the LFCN was performed twice post-operatively, the patient's symptoms persisted. The symptoms gradually resolved 12 months after the surgery. In our case, we suggest that the continuous epidural infusate caused neural ischemia of the L3 nerve root by a compressive effect.
