Machine learning for a combined electroencephalographic anesthesia index to detect awareness under anesthesia

2020

Spontaneous electroencephalogram (EEG) and auditory evoked potentials (AEP) have been suggested to monitor the level of consciousness during anesthesia. As both signals reflect different neuronal pathways, a combination of parameters from both signals may provide broader information about the brain status during anesthesia. Appropriate parameter selection and combination to a single index is crucial to take advantage of this potential. The field of machine learning offers algorithms for both parameter selection and combination. In this study, several established machine learning approaches including a method for the selection of suitable signal parameters and classification algorithms are a…

Human-Robot Cooperation for Surface Repair Combining Automatic and Manual Modes

2020

[EN] This article develops a human-robot cooperation to carry out treatments such as sanding, polishing, etc. on the surface of a known rigid object. For this purpose, a vision system is considered to get the object location to ensure not only the perpendicularity of the obot tool to the object surface but also a smooth approach of the tool to the surface. In order to add flexibility, the proposal includes the simultaneous combination of automatic and manual modes of operation. Thus, the human user can guide the robot tool to treat arbitrary areas (manual mode) and, when the operator releases the tool, the robot goes into the automatic mode to treat prior established areas. The method uses …

Preliminary Results of ERAS Protocol in a Single Surgeon Prospective Case Series

2022

Background and Objectives: The aim was to compare the intra and postoperative outcomes between the Enhanced Recovery After Surgery (ERAS) protocol versus the standard of care protocol (SCP) in patients who underwent radical cystectomy performed by a single surgeon. Materials and Methods: A retrospective comparative study was conducted including patients who underwent radical cystectomy from 2017 to 2020. Length of stay (LOS), incidence of ileus, early postoperative complications, and number of re-hospitalizations within 30 days were considered as primary comparative outcomes of the study. Results: Data were collected for 91 patients who underwent cystectomy, and 70 and 21 patients followed …

Causes and Effects of Introducing Surgery Safety Checklist: A Review

2021

The medical treatment process, particularly surgery, is inescapably bound to potential complications or undesirable adverse events. This narrative review aims to present the causes and effects of the introduction of the WHO Surgery Safety Checklist (SSC), the use of which is expected to reduce the number of perioperative errors, complications, and mortality. To achieve this objective, we performed a bibliometric analysis of medical citations indexed in the PubMed database using the SSC subject heading. Findings revealed a total of 1441 articles meeting inclusion status, with 1171 published during the last decade. After the screening of titles and abstracts, the members of the research team …

Compliance with the Surgery Safety Checklist: An Update on the Status

2022

WHO has recommended the implementation of the Surgery Safety Checklist (SSC) to reign in often simple logistic errors that lead to numerous complications, some of them being fatal, in the perioperative period. This study aims to discuss doubts presented in the medical literature concerning the effectiveness of SSC in the currently existing form. The article is based on the literature search performed in PubMed using the command phrase “Surgery Safety Checklist”. The search yielded 1,476 articles up to March 2021. Out of this group, we selected 811 articles for further detailed analysis. The selection was based on the meritorious SSC-related topicality and scrutinized content of the articles…

Italian survey on the residents' surgical level in gynecology and obstetrics

2020

Purpose: The present study aims to investigate the number of surgical procedures performed by Italian residents and their confidence to carry out different surgeries in obstetrics and gynecology. Methods: The present study is a national survey including all Italian gynecology and obstetrics senior residents. A questionnaire including 25 questions was provided. The free Google Forms site was used to create the survey. The study was conducted from April to October 2019. The survey started from the University Hospital of Parma, a tertiary hospital, and was sent to all the Italian post-graduation medical school in gynecology and obstetrics. An e-mail was sent to all representative residents in …

Letter: Tissue-Glue-Coated Collagen Sponge (TachoSil) for Minor Cerebral Dural Venous Sinus Laceration: What is the Evidence?

2015

We read with great interest the article by Gazzeri et al1 focusing on tissue-glue–coated collagen sponge (TachoSil) application to repair minor cerebral dural sinus lacerations. In their series, 57 consecutive patients were prospectively enrolled, and tears of the cerebral venous sinus were treated by TachoSil application directly to the site of the bleeding. In all patients, venous bleeding was managed initially by standard techniques for hemostasis such as compression, application of oxidized cellulose, or gelatin sponge. TachoSil application was used when standard measures failed to be effective, were excessively time- consuming or inadequate, or were considered risky. No complications r…

The Use of a Surgical Patch in the Prevention of Lymphoceles After Extraperitoneal Pelvic Lymphadenectomy for Prostate Cancer: A Randomized Prospecti…

2009

Purpose: Pelvic lymphadenectomy is frequently performed simultaneously with radical prostatectomy to determine lymph node status and the most frequently recorded postoperative complication is the development of a symptomatic lymphocele. This study evaluated TachoSil® as an adjunct treatment in preventing lymphoceles after extraperitoneal pelvic lymphadenectomy for prostate cancer. Materials and Methods: A total of 60 consecutive patients who had undergone radical prostatectomy and pelvic lymphadenectomy were prospectively enrolled in this study. The patients were randomly assigned to a standard technique with the use of clips and electrocoagulation plus TachoSil, or to standard technique on…

Resting-State Functional Magnetic Resonance Imaging for Brain Tumor Surgical Planning: Feasibility in Clinical Setting.

2019

The aim of this study was to introduce resting-state functional magnetic resonance imaging (rest-fMRI) capability for brain tumor surgical planning. rest-fMRI is an emerging functional neuroimaging technique potentially able to provide new insights into brain physiology and to provide useful information regarding brain tumors in preoperative and postoperative settings. rest-fMRI evaluates low-frequency fluctuations in the blood oxygen level–dependent signal while the subject is at rest during magnetic resonance imaging examination. Multiple resting-state networks have been identified, including the somatosensory, language, and visual networks, which are of primary importance for surgical pl…
