Randomized Controlled Trial Comparative StudyComparison of the analgesic effect of intravenous acetaminophen with that of flurbiprofen axetil on post-breast surgery pain: a randomized controlled trial.
Acetaminophen is known to be a relatively weak analgesic with fewer side effects than nonsteroidal anti-inflammatory drugs (NSAIDs). This study aimed to determine whether intravenous (iv) acetaminophen produces comparable analgesic effects to those of flurbiprofen (positive control drug), an intravenously injectable NSAID, after partial mastectomies. The primary outcome assessed was pain intensity during the first 24 h after the operation, and the secondary outcome was the satisfaction rating at discharge. ⋯ Acetaminophen produces an equivalent analgesic effect to flurbiprofen in post-partial mastectomy patients.

Multicenter StudyNon-lactate strong ion difference: a clearer picture.
The recommended method for elucidating the effects of strong ions other than lactate on acid-base balance is to calculate the non-lactate strong ion difference (SIDnl). A relationship between HCO3 (-) and SIDnl in hyperchloremic patients has already been demonstrated; in the present study, the relationships between SIDnl, the apparent strong ion difference (SIDa), and mortality at intensive care unit (ICU) admission were investigated. ⋯ SIDnl can be used to determine the effects of strong ions other than lactate on SIDa values and acid-base balance. Furthermore, a low SIDnl at ICU admission can be a prognostic indicator of mortality.

Randomized Controlled TrialImpact of anesthetic technique on the stress response elicited by laparoscopic cholecystectomy: a randomized trial.
The aim of this randomized, double-blind clinical trial was to elucidate the impact of general anesthesia alone (GA) or supplemented with epidural anesthesia (EpiGA) on surgical stress response during laparoscopic cholecystectomy, using stress hormones, glucose, and C-reactive protein (CRP), as potential markers. Sixty-two patients scheduled to undergo elective laparoscopic cholecystectomy were randomly assigned into two groups to receive either GA or EpiGA. Stress hormones [cortisol (COR), human growth hormone (hGH), prolactine (PRL)], glucose, and CRP were determined 1 day before surgery, intraoperatively, and upon first postoperative day (POD1). ⋯ Although, CRP was minimally affected intraoperatively, a notable augmentation on POD1, comparable in both groups, was recorded. These results indicate that hormonal and metabolic stress response is slightly modulated by the use of epidural block supplemented by general anesthesia, in patients undergoing laparoscopic cholecystectomy cholecystectomy. Nevertheless, inflammatory reaction as assessed by CRP seems to be unaffected by the anesthesia regimen.

Randomized Controlled TrialUltrasound-guided popliteal sciatic nerve blockade in the severely and morbidly obese: a prospective and randomized study.
Limited research data exist regarding optimal block techniques in the severely and morbidly obese patient population. We compared two approaches to sciatic nerve blockade at the popliteal fossa in severely and morbidly obese patients. The purpose of this study was to identify differences in pain scores, block onset characteristics, and adverse events between the proximal (prebifurcation) and the distal (postbifurcation) sites. ⋯ The distal approach to the popliteal block provided several intraoperative and analgesic benefits without a difference in block procedural times in the severely and morbidly obese. It is a cost-free intervention that results in a higher likelihood of a successful block in a population where avoidance of opioids is desirable.

Randomized Controlled Trial Comparative StudyEvaluation of a smartphone camera system to enable visualization and image transmission to aid tracheal intubation with the Airtraq(®) laryngoscope.
Using three-dimensional printing, we produced adaptors to attach a smartphone with camera to the eyepiece of the Airtraq(®) laryngoscope. This low-cost system enabled a team to simultaneously view the laryngoscopy process on the smartphone screen, and also enabled image transmission. We compared the Airtraq(®) with the smartphone Airtraq(®) system in a crossover study of trainee anesthesiologists performing tracheal intubation in a manikin. ⋯ In the patient study, we were able to view the larynx in all 30 patients, and the remote instructor was able to receive the images and to respond on correctness of laryngoscopy and tracheal tube placement. Tracheal intubation was successful within 90s in 19 (63 %) patients. In conclusion, use of a smartphone with the Airtraq(®) may facilitate instruction and communication of laryngoscopy with the Airtraq(®), overcoming some of its limitations.
