Balloon assisted valsalva maneuver in the diagnosis of saphenofemoral junction incompetence.

چکیده
BACKGROUND Conventional Valsalva maneuver (CV) is a standardprocedure to exhibit reverse venous flow atsaphenofemoral junction (SFJ) by duplex ultrasonography (DUS). However some patients could not undergo CV during examination. OBJECTIVE Compare blowing party balloon assisted Valsalva (PBAV) with CV for exhibiting the reverse venous flow at SFJ incompetence. MATERIAL AND METHOD Forty patients who had symptoms and signs of suspected saphenofemoral junction incompetence were examined for venous reflux by DUS with two techniques of Valsalva maneuver PBAV and CV The design was a 2x2 cross-over study. The patients were randomized to two sequences. The first sequence performed CV before PBAV The second sequence performed PBAV before CV The timing for the instruction, reflux time, and total timing of examination were compared between the two sequences. RESULTS There was neither period effect nor treatment-period interaction. Both PBAV and CV could equally identify SFJ reflux, but teaching time and total examination time in PBAV was shorter than CV. CONCLUSION PBAV is a new option to exhibit reverse venous flow at SFJ by DUS. PBAV is easier and spend less time than CV

Comparison of three methods of Valsalva maneuver, lidocaine, and Valsalva maneuvers along with administration of lidocaine to reduce the pain associated with administration of Propofol
Background: Propofol is commonly used in anesthesia practice because of its rapid recovery time, but pain upon injection is one of the unfavorable complications of this drug, which can cause both physical and mental discomfort for patients. Therefore, it is important to lower the pain on injection of Propofol in patients undergoing anesthesia. As a result, the current study was conducted in ord...

Introduction: Propofol is one of the most common anesthetic drugs. Painful injection with a reported prevalence of 28 to 90% in various studies is one of the problems of taking Propofol. The present study investigated the effect of performing the Valsalva maneuver and tourniquet twisting on pain intensity and hemodynamic changes. Materials and Methods: This clinical trial was performed on 105 p...

In order to determine the effect of Valsalva maneuver and head rotation on the internal jugular vein (IJV) diameter and cross-sectional area and overlap with the carotid artery (CA) and find the best technique for safe cannulation of the IJV and decrease the risk of CA puncture, the diameter of both the IJV and the CA and percentage of overlap between the two vessels and cross-sectional are...
متن کاملInternal jugular vein valve incompetence is highly prevalent in transient global amnesia.
BACKGROUND AND PURPOSE Transient global amnesia (TGA) is the inability to retain new information and to recall past events during a period of minutes or hours. Its etiology is unclear, and flow disturbances in the mesial temporal lobes secondary to venous congestion have been proposed as a potential cause. Ultrasonographic evaluation of the internal jugular vein (IJV) has demonstrated valvular ...
