Randomized Controlled TrialErector spinae plane versus paravertebral nerve blocks for postoperative analgesia after breast surgery: a randomized clinical trial.
Paravertebral nerve blocks (PVBs) are frequently used to treat pain during and following breast surgery, but have various undesirable risks such as pneumothorax. The erector spinae plane block (ESPB) also provides perioperative breast analgesia, but is purported to be easier to administer with a favorable safety profile. However, it remains unknown if the new ESPB provides comparable analgesia as the decades-old PVB technique. ⋯ PVBs provided superior analgesia and reduced opioid requirements following non-mastectomy breast surgery. To compare the relatively rare complications between the techniques will require a sample size 1-2 orders of magnitude greater than the current investigation; however, without a dramatic improvement in safety profile for ESPBs, it appears that PVBs are superior to ESPBs for postoperative analgesia after non-mastectomy breast surgery.

Thoracoscopic lung biopsy under regional anesthesia for interstitial lung disease.
Interstitial lung disease (ILD) management guidelines support lung biopsy-guided therapy. However, the high mortality associated with thoracoscopic lung biopsy using general anesthesia (GA) in patients with ILD has deterred physicians from offering this procedure and adopt a diagnostic approach based on high-resolution CT. Here we report that thoracoscopy under regional anesthesia could be a safer alternative for lung biopsy and effectively guide ILD treatment. ⋯ Thoracoscopy using regional anesthesia might be a safer alternative to lung biopsy in patients with ILD.

It is common practice for emergency physicians to give parenteral opioids for acute pain, however, some treating physicians have concerns that using parenteral opioids can lead to nausea and vomiting when used alone. Therefore, antiemetics are often given prophylactically with opioids for nausea and vomiting in the emergency department (ED). This systematic review evaluates the use of prophylactic antiemetics with parenteral opioids for the treatment of acute pain in the ED. ⋯ Based on the literature review, routine use of prophylactic antiemetics are not indicated with administration of parenteral opioids for treatment of acute pain in the ED, as nausea and vomiting are infrequent side effects. The recent literature clearly demonstrates that there are potential undesirable side effects from the use of antiemetics when using opioids. However, one subgroup of patients, those with a known history of nausea and vomiting after opioid use or a history of travel sickness, may benefit from the use of prophylactic antiemetic when being treated with parenteral opioids.

Does cryoneurolysis result in persistent motor deficits? A controlled study using a rat peroneal nerve injury model.
Cryoneurolysis of peripheral nerves uses localised intense cold to induce a prolonged block over multiple weeks that has the promise of providing potent analgesia outlasting the duration of postoperative pain following surgery, as well as treat other acute and chronic pain states. However, it remains unclear whether persistent functional motor deficits remain following cryoneurolysis of mixed sensorimotor peripheral nerves, greatly limiting clinical application of this modality. To help inform future research, we used a rat peroneal nerve injury model to evaluate if cryoneurolysis results in persistent deficits in motor function. ⋯ When applied to a mixed sensorimotor nerve, cryoneurolysis did not result in persistent motor deficits.
