Continuous positive airway pressure can treat sleep related groaning

Washington, Jan 2 (ANI): A new study has found that Catathrenia, (sleep related groaning) an uncommon feature of a sleep-related breathing disorder, can be successfully treated with continuous positive airway pressure (CPAP).

In the study, Christian Guilleminault, MD, of Stanford University, and colleagues focused on seven consecutive female patients between the ages of 20 and 34, all of whom had a chief complaint of involuntary groaning during sleep.

The study participants filled out questionnaires, underwent a standard clinical evaluation, a physical exam, craniofacial evaluations and a nocturnal polysomnogram.

All seven were treated with CPAP and then offered surgical treatment if they were unable to tolerate or adhere to CPAP recommendations.

It was found that three individuals had a personal history of another parasomnia in childhood, six had prior orthodontic intervention, five had tooth extraction during their teenage years, and two reported another family member with likely catathrenia.

Researchers found that CPAP treatment eliminated the groaning sound. Five patients elected subsequent surgical intervention, in which three of the four that followed up after surgery required oral appliance treatment. However, all four ultimately had resolution of groaning.

Catathrenia can be both a social problem and a sign of an underlying breathing problem during sleep, Dr. Guilleminault said.

CPAP was first introduced as a treatment option for sleep apnea in 1981.
It is the most common and effective treatment for obstructive sleep apnea (OSA).

CPAP provides a steady stream of pressurized air to patients through a mask that they wear during sleep. This airflow keeps the airway open, preventing the pauses in breathing that characterize sleep apnea and restoring normal oxygen levels.

The study is published in the January 1 issue of the journal SLEEP. (ANI)
