This study describes the implementation of a multimodal, multidisciplinary, evidence-based ERAS program in oncologic spine surgery, identifies and measures several relevant postoperative recovery outcomes, and demonstrates the feasibility and potential benefit of the program in improving analgesia and decreasing opioid consumption. The study underscores the importance of defining and capturing meaningful, patient-specific, and patient-reported outcomes, and constant evaluation and monitoring of a group's compliance with the program. The study represents the steppingstone for evaluation and improvement of a young ERAS program for spine surgery and serves as a roadmap for further initiatives and larger-scale studies.

To test the association between the use of scalp blocks for malignant brain tumor craniotomy and survival. This is a retrospective study conducted in a tertiary academic center. Demographic, intraoperative and survival data from 808 adult patients with malignant brain tumors was included in the analysis.

Article Synopsis
  • Several studies suggest that hyperglycemia (high blood sugar) during the first 10 to 12 weeks after surgery affects survival rates for patients with glioblastoma multiforme (GBM).
  • An analysis of 162 adult GBM patients who received temozolomide found that higher glucose levels before and after surgery correlated with decreased overall survival (OS).
  • Specifically, preoperative hyperglycemia showed a statistically significant link to poor OS, indicating that managing blood sugar levels may be crucial for improving outcomes after GBM surgery.

Background And Purpose: Physicians responsible for anesthesia and/or sedation (A/S) at emerging proton radiation therapy centers (PTCs) seek information about practices at established centers. We conducted a survey of A/S practices at established PTCs to provide this information for physicians at new PTCs.

Methods And Materials: A web-based survey was sent to physicians responsible for A/S at 37 established PTCs.

Enhanced recovery after surgery (ERAS) initiatives in the fields of gastrointestinal and pelvic surgery have contributed to improved postoperative functional status for patients and decreased length of stay. A similar comprehensive protocol is lacking for patients undergoing craniotomy for tumor resection. A literature search was performed using PubMed.

Background: Proton therapy is a newer modality of radiotherapy during which anesthesiologists face specific challenges related to the setup and duration of treatment sessions.

Purpose: Describe our anesthesia practice for children treated in a standalone proton therapy center, and report on complications encountered during anesthesia.

Materials And Methods: A retrospective review of anesthetic records for patients ⩽18years of age treated with proton therapy at our institution between January 2006 and April 2013 was performed.

Recent advances in cancer therapy have seen increased combinations of different treatment modalities as well as novel approaches that affect anaesthetic care. Increasingly, surgery is being combined with chemotherapy and radiation therapy. Moreover, minimally invasive procedures are gaining popularity and more targeted therapies are being used.

Background: Extensive tumor implants secondary to sarcoma, sarcomatosis, or mesothelioma in children is rare. We conducted the first phase 1 trial of escalating doses of cisplatin during hyperthermic intraperitoneal chemotherapy (HIPEC) in children with sarcomatosis. The most devastating complication of cisplatin therapy is nephrotoxicity.

Bradykinin, an endogenous nonapeptide and an important mediator of inflammation, is also implicated in the initiation and maintenance of pain. Both des-Arg(8), Leu(8)-bradykinin (dALBK) and HOE-140, the prototypic bradykinin B1 and B2 receptor antagonists, respectively, have been shown to reduce pain behaviors and inflammation in animal models of persistent nociception. We studied them for activity against incision-induced pain behaviors in a rat model for postoperative pain.
