A completed audit cycle on post-tonsillectomy haemorrhage rate: coblation versus standard tonsillectomy
Acta Oto-Laryngologica
|March 17, 2007
Summary
Abandoning coblation tonsillectomy significantly reduced secondary hemorrhage rates in patients. This study compared coblation tonsillectomy with dissection tonsillectomy, finding a notable decrease in bleeding complications after switching techniques.
Area of Science:
- Otolaryngology
- Surgical Outcomes
- Patient Safety
Background:
- Post-tonsillectomy hemorrhage remains a significant concern.
- Coblation tonsillectomy is a technique used for tonsil removal.
- Routine dissection tonsillectomy involves cold steel and diathermy.
Purpose of the Study:
- To compare the postoperative hemorrhage rates of coblation tonsillectomy versus routine dissection tonsillectomy.
- To evaluate the impact of discontinuing coblation on hemorrhage rates.
Main Methods:
- Retrospective study comparing two audit periods.
- Period 1: 441 coblation tonsillectomies reviewed (Jan-Sep 2002).
- Period 2: 416 dissection tonsillectomies reviewed after coblation was abandoned (Jul 2003-Aug 2004).
- Statistical analysis using the chi-squared test.
Main Results:
- Primary hemorrhage rates were similar between periods (1.8% vs. 1.4%, p=0.666).
- Secondary hemorrhage rates significantly decreased from 15.4% (coblation) to 5.8% (dissection) (p<0.001).
- Detailed results for adults and children are presented.
Conclusions:
- Discontinuing coblation tonsillectomy led to a significant reduction in secondary postoperative hemorrhage.
- Dissection tonsillectomy appears to be associated with lower secondary hemorrhage rates.

01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

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...

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

01:25Suctioning the Oropharyngeal Airway
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 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...
