Spontaneous subcapsular hepatic hematoma in pregnant patients.

Spontaneous subcapsular hepatic hematoma (SSHH) with or without previous history of preeclampsia and/or HELLP syndrome represents a very rare pathological condition in pregnancy and postpartum, (1/45,000-1/225,000 pregnancies). Its importance for the anesthesiologist lays in its association with high morbidity and mortality for the mother (60-86%, 39%) and newborn (42%). After a high clinical suspicion, the certainty clinical diagnosis is settled by different imaging techniques.

Buprenorphine versus dexamethasone as perineural adjuvants in femoral and adductor canal nerve blocks for total knee arthroplasty: a randomized, non-inferiority clinical trial.

Background: Optimal control of acute postoperative pain and prevention of chronic persistent pain in total knee arthroplasty (TKA) remain a challenge.

Methods: A randomized, non-inferiority clinical trial (385 patients) evaluated every hour immediate postoperative pain during 24 h, using a verbal rating 11-point scale for patient self-reporting of pain (VRS11). All patients received subarachnoid anesthesia and were randomly allocated in four groups: single shots femoral (FNB) or adductor canal blocks (ACB), both with dexamethasone (dex) and buprenorphine (bup).

A randomized clinical trial comparing six techniques of postoperative analgesia for elective total hip arthroplasty under subarachnoid anesthesia with opioids.

Background: Optimal control of acute postoperative pain and prevention of chronic persistent pain in total hip arthroplasty (THA) remain a challenge. The main hypothesis was that peripheral nerve blocks improve postoperative analgesia.

Methods: Immediate postoperative pain (24 hours) was evaluated every hour in 510 patients using a verbal rating 11-point scale for patient self-reporting of pain (VRS-11).

Reducing by 50% the incidence of maternal hypotension during elective caesarean delivery under spinal anesthesia: Effect of prophylactic ondansetron and/or continuous infusion of phenylephrine - a double-blind, randomized, placebo controlled trial.

Background: Prophylactic administrations of ondansetron or phenylephrine have been reported to provide a protective effect against hypotension in women undergoing cesarean delivery under spinal anesthesia (SA). The main hypothesis is that ondansetron improves the hemodynamic response, especially combined with phenylephrine infusion.

Methods: This prospective, double-blind, randomized, placebo-controlled study included 265 healthy pregnant women scheduled for elective cesarean delivery under SA.
