Metoprolol for prevention of bucking at orotracheal extubation: a double-blind, placebo-controlled randomised trial.

Background: Respiratory responses to extubation can cause serious postoperative complications. Beta-blockers, such as metoprolol, can interfere with the cough pathway. However, whether metoprolol can effectively control respiratory reflexes during extubation remains unclear.

Stroke with postoperative visual loss as the first clinical manifestation of antiphospholipid antibody syndrome: Case report.

Introduction: Postoperative visual loss (POVL) is a rare and devastating complication. Its incidence in nonophthamologic surgeries varies from 0.056 % to 1.

Long-term Efficacy of Pectoserratus Plane Block (PSPB) for Prevention of Post-mastectomy Pain Syndrome: Extended Follow-up From a Randomized Controlled Trial.

Objectives: Pectoserratus plane block (PSPB) leads to lower postoperative pain intensity. We examined whether PSPB could also reduce the incidence of post-mastectomy pain syndrome (PMPS) in women undergoing breast cancer surgery.

Methods: We performed an extension study of a randomized trial that compared PSPB versus control in women undergoing mastectomy.

Effects of lidocaine and esmolol on hemodynamic response to tracheal intubation: a randomized clinical trial.

Introduction And Objectives: Although lidocaine is widely used to prevent cardiovascular changes resulting from laryngoscopy and orotracheal intubation, it is still unclear whether there are more efficacious drugs. This study aimed to compare the beta-blocker esmolol with lidocaine regarding the effects on hemodynamic response after orotracheal intubation.

Methods: The study has a prospective, randomized, double-blind, superiority design, and assessed 69 participants between 18 and 70 years of age, ASA I-II, scheduled for elective or emergency surgery under general anesthesia with orotracheal intubation.

Intra-operative esmolol and pain following mastectomy: A randomised clinical trial.

Background: Esmolol is a beta-1 selective blocker that has been shown to reduce postoperative pain. Its antinociceptive effects have not been tested following mastectomy.

Objective: To evaluate the safety, efficacy and antinociception of intra-operative esmolol infusion after mastectomy.

Effect of ondansetron on spinal anesthesia-induced hypotension in non-obstetric surgeries: a randomised, double-blind and placebo-controlled trial.

Background And Objectives: Spinal anesthesia is an effective technique for many surgical procedures, but it is often associated with an increased risk of potentially deleterious hemodynamic disturbances. The benefits of prophylactic ondansetron for preventing spinal anesthesia-induced hypotension are still uncertain. Therefore, this study aimed to compare the effect of ondansetron and placebo before spinal block on the incidence of hypotension in patients having non-obstetric surgeries.

Prevalence of Inadvertent Perioperative Hypothermia and Associated Factors: A Cross-Sectional Study.

Inadvertent perioperative hypothermia, defined as a body temperature <36.0°C, is a common outcome of anesthesia that can cause serious consequences to patients. The aim of this study is to determine the prevalence of inadvertent hypothermia among surgical procedures from two referral centers in Brazil and to identify sociodemographic, clinical, or surgery-related predictors of hypothermia.

Synergistic effect of the association between lidocaine and magnesium sulfate on peri-operative pain after mastectomy: A randomised, double-blind trial.

Background: Recently, the use of venous adjuvants, such as lidocaine and magnesium sulfate, has been gaining ground in multimodal analgesia. However, no study has evaluated the impact a combination of the two drugs.

Objectives: To evaluate the efficacy of venous adjuvants in reducing opioid consumption and pain scores after mastectomy.

[Risk factors for postoperative hypothermia in the post-anesthetic care unit: a prospective prognostic pilot study].

Background: Hypothermia occurs in up to 20% of perioperative patients. Systematic postoperative temperature monitoring is not a standard of care in Brazil and there are few publications about temperature recovery in the postoperative care unit.

Design And Setting: Multicenter, observational, cross-sectional study, at Hospital de Base do Distrito Federal and Hospital Materno Infantil de Brasília.

Anesthetic management of Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (CRS/HIPEC): The importance of hydro-electrolytic and acid-basic control.

Justification And Objectives: Patients affected by gynecological or gastrointestinal tract neoplasms that evolve to peritoneal carcinomatosis experience a significant drop in their quality of life, high morbidity and short survival times with currently available chemotherapeutic schemes. The surgical treatment based on cytoreduction and the employment of hyperthermic intraperitoneal chemotherapy in the intra-operative period is a true challenge to anesthesiologist.

Case Report: A 67 years old patient diagnosed with mucinous adenocarcinoma of the Appendix associated with mucinous carcinomatosis, was submitted to cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), under general anesthesia and epidural block.

Effects of lidocaine and magnesium sulfate in attenuating hemodynamic response to tracheal intubation: single-center, prospective, double-blind, randomized study.

Background And Objectives: Hemodynamic response to airway stimuli is a common phenomenon and its management is important to reduce the systemic repercussions. The objective of this study is to compare the efficacy of intravenous magnesium sulfate versus lidocaine on this reflex hemodynamics after laryngoscopy and tracheal intubation.

Methods: This single-center, prospective, double-blind, randomized study evaluated 56 patients ASA 1 or 2, aged 18-65 years, scheduled for elective surgeries under general anesthesia with intubation.

[Dissection of the wired endotracheal tube's lumen during general anesthesia: a case report].

Objective: The aim of this study is to report a case of a clinically significant obstruction during mechanical ventilation caused by the dissection of the wired endotracheal tube's lumen during general anesthesia in a pediatric patient.

Case Report: A12-years old patient undergoing general anesthesia for open appendectomy was intubated with a wired endotracheal tube and difficult removal of the guide. After starting the mechanical ventilation, there was increased expiratory fraction of CO and need for increased inspiratory pressure.
