The Effect of Povidone-iodine Ophthalmic Surgical Prep Solution on Respiration in Children Undergoing Strabismus Surgery With General Anesthesia.

Strabismus Clinical Trial

Official title:
The Effect of Povidone-iodine Ophthalmic Surgical Prep Solution on Respiration in Children Undergoing Strabismus Surgery With General Anesthesia.

Clinical Trial Summary

Determine whether the application of povidone-iodine ophthalmic solution onto the ocular surface causes a change in respiration in children undergoing strabismus surgery with general anesthesia.

Hypothesis: The application of povidone-iodine ophthalmic solution to the ocular surface causes a change in respiration in children during general anesthesia prior to strabismus surgery.

Clinical Trial Description

The study is randomized and single blind. One hundred children were randomly assigned to have either povidone-iodine (group A) or balanced salt solution (BSS) (group B) eye drops instilled into their eyes during anesthesia just prior to strabismus surgery. After induction of anesthesia and insertion of an LMA while the patient was at a steady state of anesthesia and spontaneously breathing sevoflurane in oxygen, 3 drops of either povidone-iodine or BSS was instilled into each eye (right eye first). Respiratory rate was determined by measuring the peak-to-peak interval on the capnograph. This is similar to calculating heart rate by measuring the R-R interval on an ECG. HR, BP, SaO2, EtCO2, and expired sevoflurane were measured in each patient. Medical history information collected included history of prior surgeries, co-existing diseases, or apnea. Appropriate statistical analyses were performed for comparisons between the groups with respect to respiratory rate, HR, BP, expired sevoflurane, and co-existing diseases. ;
