Randomized Controlled Trial Comparative Study
Comparison of analgesic efficacy of four-quadrant transversus abdominis plane (TAP) block and continuous posterior TAP analgesia with epidural analgesia in patients undergoing laparoscopic colorectal surgery: an open-label, randomised, non-inferiority trial.
Four-quadrant transversus abdominis plane block with bilateral posterior TAP catheters for 48 hours provides analgesia equivalent to epidural analgesia in patients having laparoscopic colorectal surgery.

Randomized Controlled Trial
Prophylactic vs therapeutic blood patch for obstetric patients with accidental dural puncture - a randomised controlled trial.
Epidural blood patch is a standard treatment for obstetric patients experiencing a severe post-dural puncture headache. Patients who sustained an accidental dural puncture during establishment of epidural analgesia during labour or at caesarean delivery were randomly assigned to receive a prophylactic epidural blood patch or conservative treatment with a therapeutic epidural blood patch if required. ⋯ The number of patients who needed a second blood patch did not differ significantly between the two groups: 6 (10.0%) for prophylactic epidural blood patch and 4 (11.1%) for therapeutic epidural blood patch. We conclude that prophylactic epidural blood patch is an effective method to reduce the development of post-dural puncture headache in obstetric patients.

Drawing samples from an indwelling arterial line is the method of choice for frequent blood analysis in adult critical care areas. Sodium chloride 0.9% is the recommended flush solution for maintaining the patency of arterial catheters, but it is easy to confuse with glucose-containing bags on rapid visual examination. The unintentional use of a glucose-containing solution has resulted in artefactually high glucose concentrations in blood samples drawn from the arterial line, leading to insulin administration causing hypoglycaemia and fatal neuroglycopenic brain injury. ⋯ We also make recommendations about storage, arterial pressure monitoring and sampling systems and techniques. Finally, we make recommendations about glucose monitoring and insulin administration. It is intended that adherence to these guidelines will reduce the frequency of sample contamination errors in arterial line use and capture events, when they do occur, before they cause patient harm.
