Appropriateness of recommended chest compression depths for cardiopulmonary resuscitation based on chest computed tomography parameters among Thai population: A multicenter retrospective study.

Aim: We evaluated the appropriateness of various chest compression (CC) depths among Thai population by comparing the calculated heart compression fraction (HCF) using mathematical methods based on chest computed tomography (CT) measurements.

Methods: This multicenter retrospective cross-sectional study was conducted from September 2014 to December 2020. Chest parameters included external anteroposterior diameter (EAPD), internal anteroposterior diameter (IAPD), heart anteroposterior diameter (HAPD), and non-cardiac soft tissue measured at the level of maximum left ventricular diameter (LVmax).

Optimal chest compression position for cardiopulmonary resuscitation determined by computed tomography image: retrospective cross-sectional analysis.

The objective of this study was to determine the height of optimal hand position for chest compression during adult cardiopulmonary resuscitation (CPR) from the tip of the sternal xiphoid process (TOX) along with the relative heights of the left ventricular outflow tract (LVOT) and abdominal organs among the Thai population. The retrospective cross-sectional study was conducted through a review of medical records and contrast-enhanced chest computed tomography. The total of 204 Thai patients without obvious chest deformity at Ramathibodi Hospital from January to June 2018 was included as part of a multi-regional study.

Using computed tomography to evaluate proper chest compression depth for cardiopulmonary resuscitation in Thai population: A retrospective cross-sectional study.

Introduction: The effectiveness of cardiopulmonary resuscitation is determined by appropriate chest compression depth and rate. The American Heart Association recommended CC depth at 5-6 cm to indicate proper cardiac output during cardiac arrest. However, many studies showed the differences in the body builds between Caucasians and Asians.

Usefulness and outcome of whole-body computed tomography (pan-scan) in trauma patients: A prospective study.

Background: Severe trauma can cause multi-organ injuries, and the mortality rate may increase if significant organ injuries are missed. This study was performed to determine whether whole-body computed tomography scan (pan-scan) can detect significant injury and leads to proper management, including alteration the priority of management.

Methods: This prospective study was conducted from January 2019 to March 2021 and involved trauma patients level 1, level 2, and dangerous mechanism of trauma.

Diagnostic properties of a portable near-infrared spectroscopy to detect intracranial hematoma in traumatic brain injury patients.

Traumatic brain injury (TBI) is a major public health issue worldwide. A portable near-infrared spectroscopy (NIRS) is a non-invasive device to detect intracranial hematoma. The advantages of the NIRS include real time results and non-radiation exposure.

Diagnostic accuracy of triple-contrast multi-detector computed tomography for detection of penetrating gastrointestinal injury: a prospective study.

Purpose: Neither the performance of CT in diagnosing penetrating gastrointestinal injury nor its ability to discriminate patients requiring either observation or surgery has been determined.

Materials And Methods: This was a prospective, single-institutional observational study of patients with penetrating injury to the torso who underwent CT. Based on CT signs, reviewers determined the presence of a gastrointestinal injury and the need for surgery or observation.

Reducing emergency CT radiation doses with simple techniques: A quality initiative project.

Introduction: Use of indication-specific CT protocols and adjustment of scan parameters to decrease radiation exposure may result in significant dose reduction. We implemented these strategies and compare pre- and post-implementation radiation dose in emergency department (ED) patients.

Method: This was a descriptive, retrospective study.

Trauma Ultrasound.

Ultrasound plays a pivotal role in the evaluation of acute trauma patients through the use of multi-site scanning encompassing abdominal, cardiothoracic, vascular and skeletal scans. In a high-speed polytrauma setting, because exsanguinations are the primary cause of trauma morbidity and mortality, ultrasound is used for quick and accurate detection of hemorrhages in the pericardial, pleural, and peritoneal cavities during the primary Advanced Trauma Life Support (ATLS) survey. Volume status can be assessed non-invasively with ultrasound of the inferior vena cava (IVC), which is a useful tool in the initial phase and follow-up evaluations.

Lethal now or lethal later: The natural history of Grade 4 blunt cerebrovascular injury.

Background: Grade 4 blunt cerebrovascular injury (BCVI4) has a known, significant rate of stroke. However, little is known about the natural history of BCVI4 and the pathophysiology of subsequent stroke formation.

Methods: A 4-year review of patients with BCVI4 at the R Adams Cowley Shock Trauma Center was performed.

Blunt splenic injury: use of a multidetector CT-based splenic injury grading system and clinical parameters for triage of patients at admission.

Purpose: To assess the use of a dual-phase multidetector computed tomography (CT)-based grading system alone and in combination with assessment of clinical parameters at triage of patients with blunt splenic injury for determination of appropriate treatment (observation, splenic artery embolization [SAE], or splenic surgery).

Materials And Methods: This HIPAA-compliant retrospective study was approved by the institutional review board, and the requirement for informed consent was waived. Between January 2009 and July 2011, 171 hemodynamically stable patients with blunt splenic injury underwent multidetector CT at admission to the hospital.

Arterial injuries after penetrating brain injury in civilians: risk factors on admission head computed tomography.

Object: The object of this study was to determine the specific CT findings of the injury profile in penetrating brain injury (PBI) that are risk factors related to intracranial arterial injuries.

Methods: The authors retrospectively evaluated admission head CTs and accompanying digital subtraction angiography (DSA) studies from patients with penetrating trauma to the head in the period between January 2005 and December 2012. Two authors reviewed the CT images to determine the presence or absence of 30 injury profile variables and quantified selected variables.

Traumatic optic neuropathy prediction after blunt facial trauma: derivation of a risk score based on facial CT findings at admission.
