Patterned Screen‐Printing Process for Substrate‐Free and Scalable Hyaluronic Acid Microneedle Arrays
Advanced Materials Technologies, EarlyView.A substrate‐free microneedle array comprising a hybrid hyaluronic acid ink was fabricated via a scalable screen‐printing process for flexible transdermal drug delivery. Defect‐free mold filling was achieved using a vacuum‐assisted jig and a delayed drying system, and the use of this versatile platform for multi‐drug patterning and ex vivo skin ...

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space
Advanced Materials Technologies, EarlyView.Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

From Rigid to Soft Robotic Approaches for Neuroendoscopy
Advanced Robotics Research, EarlyView.Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Waveguide Photoactuators: Materials, Fabrication, and Applications
Advanced Robotics Research, EarlyView.Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Blood loss in surgical oncology: Neglected quality indicator?
Journal of Surgical Oncology, 2009AbstractQuality indicators can be defined as “specific and measurable elements of practice that can be used to assess the quality of care”. Surgical blood loss is one of the most significant perioperative predictors of patient outcome. Blood loss is a modifiable quality indicator for oncologic cancer surgery.

Surgical Blood Loss in Abdominal Hysterectomy
Gynecologic Oncology, 2001The aim of this study was to evaluate additional error in estimating red cell loss during abdominal hysterectomy.Eighty patients admitted consecutively for abdominal hysterectomy were recruited. The surgeries were done after heparinizing the suction tubing system to prevent clotting and reducing the vacuum pressure to reduce red cell lysis.

BLOOD DETERMINATION AND ESTIMATION OF BLOOD LOSS DURING SURGICAL OPERATIONS
Archives of Surgery, 1948THE CONDITION of the surgical patient postoperatively depends on several factors, among which are surgical trauma, length of operation, type of anesthesia and loss of blood. The more closely each of these factors can be maintained to normal, the more rapid will be the patient's recovery.
