Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

2.3K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Suctioning the Oropharyngeal Airway

1.6K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Tracheostomy Suctioning I: Pre-Procedural Steps

3.6K
Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

Tracheostomy Suctioning II: Procedure

3.5K
Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Pressure Relationships in Thoracic Cavity01:24

Pressure Relationships in Thoracic Cavity

8.9K
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs...

Summary
This summary is machine-generated.

Obstetricians often use excessive traction force during vacuum-assisted delivery. Objective measurement and feedback can help clinicians better estimate and manage the force applied during vacuum extraction.

Area of Science:

  • Obstetrics and Gynecology
  • Medical Device Technology
  • Patient Safety

Background:

  • Vacuum extraction is a common obstetric procedure.
  • Accurate assessment of applied force is crucial for safe delivery.
  • Previous studies have not fully quantified traction forces in clinical settings.

Purpose of the Study:

  • To investigate and quantify the traction force used during vacuum extractions.
  • To compare estimated forces with objectively measured forces.
  • To explore the relationship between traction force and adverse perinatal outcomes.

Main Methods:

  • Observational cross-sectional study involving 200 women undergoing vacuum extraction.
  • Measurement of applied force using a specially adapted device in a clinical setting.
  • Comparison with forces estimated and measured in a simulated setting with 130 obstetricians.

Main Results:

  • Median peak forces ranged from 176 N to 241 N, with 34% of cases exceeding 216 N.
  • Excessive traction force was associated with three of four cases of mild hypoxic ischaemic encephalopathy.
  • Obstetricians underestimated applied force, with measured clinical forces four times higher than estimated simulated forces.

Conclusions:

  • Traction forces applied during vacuum extraction often exceed expected levels.
  • Obstetricians tend to underestimate the force they exert during vacuum-assisted delivery.
  • Objective measurement and real-time feedback are recommended to improve force management and patient safety.
