Active clinical trials for "Funnel Chest"

Preoperative fasting is intended to lower the amount of gastric contents in order to decrease the incidence of aspiration associated with endotracheal intubation. However, recent studies show that longer fasting time does not reduce aspiration associated complications. Especially in pediatric patients, long fasting time increases patients' unpleasantness and therefore increases postoperative recovery quality. It also induces hypoglycemia. In many studies, ingesting clear liquids 2 hours up to general anesthesia decreases gastric contents and therefore the incidence of aspiration pneumonia, postoperative nausea and vomiting. Therefore anesthesiologist associations in the US and Europe recommend to drink small amount of clear liquid (water) up to 2 hours before the surgery. Nuss bar operation, or repair surgery of pectus excavatum is mostly done in pediatric patients. The procedure itself is very painful, requiring paramount amount of analgesics. Use of opioid analgesics increases postoperative nausea and vomiting. In this study, our aim is to evaluate preoperative fasting time and how preoperative supplement of clear liquid affects the quality of recovery postoperatively.

This is a prospective randomized double-blind non-inferiority trial designed to test the hypothesis that erector spinae plane block (ESPB) is non-inferior to thoracic paravertebral block (TPVB) in postoperative pain control after pectus excavatum repair.

The aim of the current study was to compare the effects of sevoflurane and desflurane on respiratory mechanics in patients undergoing repair of pectus excavatum.

In most pectus excavatum (PE) patients an underlying genetic defect is not found with molecular analysis, as a direct genetic link with PE has yet to be found and because potential underlying genetic disorders are quite rare. Only one-fifth of all PE cases are identified in the first decade of life and thus of congenital origin making younger PE patients a unique patient group. Therefore, the research question is; is early-onset pectus excavatum (PE) more likely to be part of a genetic defect than PE which became apparent during puberty or adolescence?

Pectus excavatum (PE) is the most common anterior chest wall deformity. Currently, a chest radiography (CR) or Computed Tomography (CT) scan is acquired to determine and objectify pectus severity using the Haller Index. Alongside other determinants, the Haller Index value is used in the proces of clinical decision making and determine surgical candidacy. However, cross-sectional imaging based calculation of the Haller Index implies exposure to ionizing radiation that should be limited at all times to diminish the cumulative long-term risks of malignancy. Especially in pectus patients that often concerns children. Three-dimensional (3D) optical surface imaging offers a non-invasive, radiation-free alternative that may be used to obtain thoracic measures and determine pectus severity. However, for 3D images/scans to be used as a diagnostic tool in the proces of clinical decision making and determine surgical candidacy, its diagnostic accuracy should be evaluated. This will be investigated utilizing a pilot study design as no prior accuracy studies are available.

This study will be conducted to determine the advantages and limitations of sonography compared with chest radiography, in the detection of post procedure iatrogenic pneumothorax in patients underwent to Pectus Excavatum (PE) with Nuss repair.

A retrospective chart review study analyzing the benefits of patient controlled analgesia, thoracic epidural analgesia, and paravertebral nerve block catheters in patients having surgical repair of pectus excavatum using the Nuss procedure.

Breathing movements, called chest wall motion, are very complex. The investigators are studying how movement of the abdomen, ribs and diaphragm contribute to breathing and how this differs with different diseases in the chest. Breathing movements may help with diagnosis, assessment of severity or assessing the impact of treatments for chest conditions. The investigators are following people who have a chest disease, measuring their chest wall motion and comparing it to their diagnosis and and how their treatment works. Chest wall motion can be measured in different ways at rest and whilst exercising. Small stickers on the chest can be used to reflect infra red light or visible squares of light can be shone onto the chest without using stickers.

The primary objective of this study is to describe the relative distances between patient clinical profiles (i.e. patient clustering) in multivariate space.

The purpose of this study is to determine whether there is a metal wear debris after minimally invasive repair of pectus excavatum and if there's a clinical relevance. Our hypothesis is that the metal bar after minimally invasive repair of pectus excavatum leads to a locally and systemic immune reaction due to elevated metal contamination.
