Hormonal aspects of suction drainage after thyroidectomy
Surgery, Gynecology & Obstetrics
|September 1, 1979
Summary
Thyroidectomy drainage fluid contains higher thyroxine levels than serum, potentially causing significant hormone loss. While drainage offers benefits, eliminating it could prevent this loss.
Area of Science:
- Endocrinology
- Surgical Research
Background:
- Suction drainage is commonly used after thyroidectomy.
- The impact of drainage fluid on thyroid hormone levels is not fully understood.
Purpose of the Study:
- To quantify thyroxine levels in thyroidectomy drainage fluid.
- To assess the impact of this loss on overall serum thyroxine.
- To evaluate the clinical significance of drainage in thyroidectomy.
Main Methods:
- Measurement of drainage fluid volume and thyroxine concentration.
- Comparison of fluid thyroxine levels with serum thyroxine.
- Calculation of daily thyroxine loss and its percentage of the total serum thyroxine pool.
- Monitoring of serum thyroxine levels post-operation.
Main Results:
- Drainage volume varied (0-92.5 mL).
- Thyroxine levels in drainage fluid were higher than serum (average 14.0 µg/100 mL).
- Daily thyroxine loss could reach 11.6% of the total serum thyroxine pool.
- Serum thyroxine normalized to an average euthyroid level (6.09 µg/100 mL) by day 21.
Conclusions:
- Thyroidectomy drainage can lead to significant thyroxine loss.
- The benefits of drainage may be outweighed by potential hormone loss.
- Eliminating drainage could prevent thyroxine loss, though no exfoliated cells were found.

01:20Synthesis and Regulation of Thyroid Hormones
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

01:26Endoscopic Studies II: Thoracocentesis
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...

01:26Tracheostomy Suctioning I: Pre-Procedural Steps
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.

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.

01:23Tracheostomy Suctioning II: Procedure
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...
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...
