High mobilization of CD133+/CD34+ cells expressing HIF-1α and SDF-1α in septic abdominal surgical patients.

BMC Anesthesiol 2020 Jun 27;20(1):158. Epub 2020 Jun 27.

Department of Anesthesia and Intensive care, University Hospital of Foggia, Foggia, Italy.

Background: The control of endothelial progenitor cells (CD133+/CD34+ EPCs) migrating from bone marrow to peripheral blood is not completely understood. Emerging evidence suggests that stromal cell-derived factor-1α (SDF-1α) mediates egression of EPCs from bone marrow, while the hypoxia inducible factor (HIF) transcriptional system regulates SDF-1α expression. Our study aimed to investigate the time course of circulating CD133+/CD34+ EPCs and its correlation with the expression of HIF-1α protein and SDF-1α in postoperative laparoscopic abdominal septic patients.

Authors:
Xuechao Hao Wei Wei

BMC Anesthesiol 2020 Jun 27;20(1):159. Epub 2020 Jun 27.

Department of Anesthesiology, The Research Unit of Perioperative Stress Assessment and Clinical Decision (2018RU012), Chinese Academy of Medical Sciences, West China Hospital, Sichuan University, 610041, Chengdu, People's Republic of China.

Background: For infants undergoing complex cardiac surgery, hemodynamic management after cardiopulmonary bypass (CPB) is challenging because of severe myocardial edema, vasomotor dysfunction and weak tolerance to a change in blood volume. More importantly, the lack of availability of equipment for advanced monitoring, such as transesophageal echocardiography or transthoracic echocardiography, restricts the accurate assessment of hemodynamics.

Case Presentation: This is a case of severe hypotension and non-detectable pulse oxygen saturation (SpO) after CPB in a low-weight infant who had normal blood pressure and oxygen saturation before surgery. Read More

Conversion of I-gel to definitive airway in a cervical immobilized manikin: Aintree intubation catheter vs long endotracheal tube.

BMC Anesthesiol 2020 Jun 18;20(1):152. Epub 2020 Jun 18.

Department of Anaesthesiology and Pain Medicine, Ajou University School of Medicine, 164, World cup-ro, Yeongtong-gu, Suwon, 16499, South Korea.

Background: After prehospital insertion of i-gel, a popular supraglottic airway (SGA), fiberoptic-guided intubation through i-gel is often required to switch the i-gel to a definitive airway for anticipated difficult airway. The Aintree intubation catheter (AIC) was developed for this purpose yet it requires many procedural steps during which maintenance of adequate ventilation is difficult. We custom-made a long endotracheal tube (LET) which may facilitate this procedure and compared the efficacy of the AIC and LET in a cervical immobilized manikin. Read More

Modified-ramped position: a new position for intubation of obese females: a randomized controlled pilot study.

BMC Anesthesiol 2020 Jun 17;20(1):151. Epub 2020 Jun 17.

Department of anesthesia and critical care medicine, Cairo university, Giza, Egypt.

Background: Endotracheal intubation requires optimum position of the head and neck. In obese females, the usual ramped position might not provide adequate intubating conditions. We hypothesized that a new position, termed modified-ramped position, during induction of anesthesia would facilitate endotracheal intubation through bringing the breasts away from the laryngoscope and would also improve the laryngeal visualization.

The effect of 1% glucose loading on metabolism in the elderly patients during remifentanil-induced anesthesia: a randomized controlled trial.

BMC Anesthesiol 2020 Jun 6;20(1):143. Epub 2020 Jun 6.

Department of Anesthesiology, Graduate School of Biomedical Sciences, Tokushima University, 3-18-15 Kuramoto, Tokushima, 770-8503, Japan.

Background: Previous studies showed that remifentanil-induced anesthesia can inhibit surgical stress response in non-diabetic adult patients and that low-dose glucose loading during anesthesia may attenuate fat catabolism. However, little is known about the influence of glucose loading on metabolism in elderly patients, whose condition may be influenced by decreased basal metabolism and increased insulin resistance. We hypothesized that, in elderly patients, intraoperative low glucose infusion may attenuate the catabolism of fat without causing harmful hyperglycemia during remifentanil-induced anesthesia.

Acute kidney injury risk prediction score for critically-ill surgical patients.

BMC Anesthesiol 2020 Jun 3;20(1):140. Epub 2020 Jun 3.

Anesthesiology Department, Faculty of Medicine Vajira Hospital, Navamindradhiraj University, Bangkok, Thailand.

Background: There has been a global increase in the incidence of acute kidney injury (AKI), including among critically-ill surgical patients. AKI prediction score provides an opportunity for early detection of patients who are at risk of AKI; however, most of the AKI prediction scores were derived from cardiothoracic surgery. Therefore, we aimed to develop an AKI prediction score for major non-cardiothoracic surgery patients who were admitted to the intensive care unit (ICU). Read More

Dural sac cross-sectional area is a highly effective parameter for spinal anesthesia in geriatric patients undergoing transurethral resection of the prostate: a prospective, double blinded, randomized study.

BMC Anesthesiol 2020 Jun 3;20(1):139. Epub 2020 Jun 3.

Department of Anesthesiology, The Affiliated AnQing Hospitals of Anhui Medical University, 352th, Renming Road, AnQing, 246003, AnHui province, China.

Background: Spinal anesthesia is optimal choice for transurethral resection of the prostate (TURP), but the sensory block should not cross the T10 level. With advancing age, the sensory blockade level increases after spinal injection in some patients with spinal canal stenosis. We optimize the dose of spinal anesthesia according to the decreased ratio of the dural sac cross-sectional area (DSCSA), the purpose of this study is to hypothesis that if DSCSA is an effective parameter to modify the dosage of spinal anesthetics to achieve a T10 blockade in geriatric patients undergoing TURP.

Awake intubation and extraluminal use of Uniblocker for one-lung ventilation in a patient with a large mediastinal mass a case report.

BMC Anesthesiol 2020 May 25;20(1):125. Epub 2020 May 25.

Department of Anesthesiology, The First Hospital of Qinhuangdao, N.O. 258, Wenhua Road, Qinhuangdao, Hebei, China.

Background: The anesthesia of patients with large mediastinal mass is at high-risk. Avoidance of general anesthesia in these patients is the safest option, if this is unavoidable, maintenance of spontaneous ventilation is the next safest technique. In these types of patients, it is not applicable to use double-lumen tube (DLT) to achieve one-lung ventilation (OLV) because the DLT has a larger diameter and is more rigid than single-lumen tube (SLT), so the mass may rupture and bleed during intubation.
