Randomized Controlled Trial Comparative StudyIntravenous and subcutaneous tramadol for inguinal herniorrhaphy: comparative study.
Inguinal herniorrhaphy is one of the most common surgeries in men. Neuroaxis block is the anesthetic technique used more often and in the majority of the cases the patient is ready to be discharged from the hospital a few hours after the procedure, as long as satisfactory analgesia is present and nausea and vomiting are absent. Tramadol is an analgesic drug that can be used in postoperative analgesia, but it has important side effects, such as nausea and vomiting whose incidence can range from 0% to 50%. The objective of the present study was to compare the incidence of nausea and vomiting and the quality of postoperative analgesia of subcutaneous and intravenous tramadol in patients undergoing inguinal herniorrhaphy. ⋯ The present study demonstrates the absence of statistically significant differences regarding the incidence of nausea and vomiting and quality of analgesia when using intravenous and subcutaneous Tramadol.

Randomized Controlled TrialRopivacaine in peribulbar anesthesia - vasoconstrictive properties.
Peribulbar anesthesia can reduce ocular blood flow (OBF) by increasing intraocular pressure (IOP) or due to the action of drugs. Ropivacaine has low toxicity and intrinsic vasoconstrictive properties, yet to be proven on the ocular vasculature. Measurements of ocular pulse amplitude (OPA) allow the indirect evaluation of the OBF. The objective of the present study was to evaluate through the OBF the vasoconstrictive properties of ropivacaine in peribulbar anesthesia. ⋯ Ropivacaine reduced more intensely the ocular pulse amplitude despite little changes in IOP and OPP. The reduction in ocular blood flow caused by ropivacaine can be attributed to its vasoconstrictive effect.

Case ReportsAnesthesia for peritonectomy with hyperthermic intraoperative peritoneal chemotherapy. Case report.
Pseudomyxoma peritonei is a rare condition related to epithelial neoplasia of the appendix and ovaries. Surgical cytoreduction, peritonectomy, and hyperthermic intraoperative peritoneal chemotherapy (HIPEC) is the treatment of choice. Maintenance of normovolemia, normothermia, postoperative pain management and coagulation status are all responsibility of the anesthesiologist. The objective of this report was to describe a case of peritonectomy with HIPEC. ⋯ Surgical cytoreduction and peritonectomy with HIPEC goes back to the decade of 1990 with several studies showing a significant increase in survival. Due to the complexity of the procedure and large surgery the vigilance of the anesthesiologist is fundamental for maintenance of clinical and laboratorial parameters, and recognition and treatment of any changes.

The clinical use of a lipid propofol formulation causes pain during injection, allergic reactions, and bacterial growth. Propofol has been reformulated in different non-lipid presentations to reduce the incidence of adverse effects, but those changes can modify its pharmacokinetics and pharmacodynamics. In the present study, we investigate the pharmacology and toxicology of lipid propofol (CLP) and the non-lipid nanoemulsion (NLP). ⋯ Non-lipid formulation of propofol can be a better alternative to CPL for intravenous anesthesia with fewer adverse effects.

Clinical TrialEvaluating the depth of the epidural space with the use of ultrasound.
The objective of the present study was to evaluate the use of the ultrasound on the determination of the depth of the epidural space. ⋯ The ultrasound is a precise tool to determine the depth of the epidural space.
