Intraoperative suction test as a predictor of velopharyngeal competence
1University of Miami School of Medicine, FL 33125.
Summary
A new intraoperative test accurately predicts speech outcomes after cleft palate surgery. This simple, inexpensive method helps determine if further surgery will be needed, achieving 92% accuracy.
Area of Science:
- Speech Surgery
- Craniofacial Anomalies
Background:
- Cleft palate and pharyngeal flap surgery can impact speech development.
- Predicting speech outcomes is crucial for surgical planning and patient management.
Purpose of the Study:
- To describe a simple, inexpensive intraoperative test for estimating speech development probability after cleft palatal or pharyngeal flap surgery.
- To evaluate the test's predictive value in a clinical setting.
Main Methods:
- A novel intraoperative test was developed and applied.
- Results were retrospectively reviewed in 151 patients over a 10-year period.
- Positive predictive values for key outcomes were calculated.
Main Results:
- The test demonstrated a 92% positive predictive value for avoiding further surgery.
- The test showed an 83% positive predictive value for the development of adequate speech.
- The findings suggest the test is a reliable predictor of speech outcomes.
Conclusions:
- The described intraoperative test is a valuable tool for predicting speech development post-cleft surgery.
- Its simplicity and low cost make it practical for routine clinical use.
- The test aids in surgical decision-making and managing patient expectations regarding speech.

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.

01:23Tracheostomy 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...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
