Can the descending aortic stroke volume be estimated by transesophageal descending aortic photoplethysmography?
The aim of this study was to investigate the ability of transesophageal photoplethysmography detected from the descending aorta (dPPG) for predicting low descending aortic stroke volume (dSV) level in cardiac surgical patients. ⋯ The AC and AUC extracted from the dPPG signal provided a sensitive and qualitative prediction for dSV level. The dSV value could not be accurately measured by dPPG metrics.

ReviewPrevention of chronic post-surgical pain: the importance of early identification of risk factors.
Chronic post-surgical pain (CPSP) is currently an inevitable surgical complication. Despite the advances in surgical techniques and the development of new modalities for pain management, CPSP can affect 15-60% of all surgical patients. The development of chronic pain represents a burden to both the patient and to the community. ⋯ Unfortunately, evidence about any effective actions to reduce this condition is limited. This review will focus on providing context to the challenging problem of CPSP. The possible role of both the surgeon and anesthesiologist in reducing the incidence of this problem will be explored.

Randomized Controlled TrialLow-dose carperitide (α-human A-type natriuretic peptide) alleviates hemoglobin concentration decrease during prolonged oral surgery: a randomized controlled study.
Surgical injury stimulates the renin-angiotensin-aldosterone system (RAAS) and causes antidiuresis, leading to postoperative oliguria. Carperitide (α-human A-type natriuretic peptide) is a cardiac peptide hormone secreted from the atrium. This peptide hormone enhances diuresis by suppressing the RAAS. In our experience, carperitide alleviates decreased hemoglobin (Hb) concentration during elective surgery. In the current study, we investigated the relationship between low-dose carperitide (0.01 µg/kg/min) and Hb concentration during oral surgery. ⋯ The Hb concentration in the group administered low-dose carperitide at 0.01 µg/kg/min remained higher than that in the control group during surgery. Administration of low-dose carperitide may therefore reduce the risk of blood transfusion during surgery.

Randomized Controlled Trial Comparative StudyComparison of ease of administration of intranasal midazolam spray and oral midazolam syrup by parents as premedication to children undergoing elective surgery.
The efficacy of midazolam as premedication in children for providing pre-operative sedation and reducing parental separation anxiety has been well established. Many studies have compared the effectiveness and medication acceptance of midazolam via oral and intranasal routes. In this study, we have compared the ease of administration of oral midazolam syrup and intranasal midazolam spray as premedication, administered by parents to children. ⋯ Oral midazolam syrup is easier for parents to administer and has better medication acceptance in children when compared to intranasal midazolam spray.

ReviewPerioperative risk factors for death among patients with symptomatic pulmonary thromboembolism.
Perioperative pulmonary thromboembolism (PTE) is a fatal complication that may occur in patients who are undergoing surgery. This study aimed to identify risk factors for PTE-related death. This study evaluated data for the most recent 5-year period (2007-2011) from the Japanese Society of Anesthesiologists' database of patients who experienced perioperative PTE. ⋯ Logistic regression analyses revealed that male sex, an age of ≥ 80 years, bedridden status, heart failure, and the non-use of anticoagulant therapy were independent risk factors for PTE-related death. We found that male sex, an age of ≥ 80 years, bedridden status, heart failure, and the non-use of anticoagulant therapy were independent risk factors for perioperative PTE-related death. Therefore, appropriate interventions for bedridden patients and thromboprophylaxis using anticoagulants may help reduce the incidence of perioperative PTE-related mortality.
