41. Balloon assisted valsalva maneuver in the diagnosis of saphenofemoral junction incompetence. (Abstract)

Balloon assisted valsalva maneuver in the diagnosis of saphenofemoral junction incompetence. 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.Compare blowing party balloon assisted Valsalva (PBAV) with CV for exhibiting the reverse venous flow at SFJ incompetence.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.There was neither period effect nor treatment-period interaction. Both PBAV and CV could

43. Hemodynamic responses during and after multiple sets of stretching exercises performed with and without the Valsalva maneuver Full Text available with Trip Pro

Hemodynamic responses during and after multiple sets of stretching exercises performed with and without the Valsalva maneuver This study investigated the acute hemodynamic responses to multiple sets of passive stretching exercises performed with and without the Valsalva maneuver.Fifteen healthy men aged 21 to 29 years with poor flexibility performed stretching protocols comprising 10 sets of maximal passive unilateral hip flexion, sustained for 30 seconds with equal intervals between sets (...) . Protocols without and with the Valsalva maneuver were applied in a random counterbalanced order, separated by 48-hour intervals. Hemodynamic responses were measured by photoplethysmography pre-exercise, during the stretching sets, and post-exercise.The effects of stretching sets on systolic and diastolic blood pressure were cumulative until the fourth set in protocols performed with and without the Valsalva maneuver. The heart rate and rate pressure product increased in both protocols, but no additive

46. A unique case of valsalva retinopathy in a conch blower Full Text available with Trip Pro

A unique case of valsalva retinopathy in a conch blower Valsalva hemorrhagic retinopathy is a form of preretinal hemorrhage that develops after a valsalva maneuver, leading to rupture of the superficial retinal capillaries. Here, we report a case of valsalva retinopathy secondary to blowing a conch, the first case report of its kind. The patient blew conch, which was part of his daily ritual to pray to God as he was a Hindu priest.A 58-year-man developed an acute decrease in vision to 5/60 (...) in his right eye after blowing the conch while performing "Puja," which is the act of praying to God in Hindu culture. Ophthalmoscopy showed a fresh preretinal hemorrhage over the macula in his right eye. YAG laser membranotomy was performed, and his vision returned to 6/6.Conch "Shankha" is a religious instrument used routinely in Hindu culture. Its mechanism is very much similar to that of a wind instrument. This is the first case report of valsalva retinopathy caused by conch blowing.

56. Comparison of Force Exerted on the Sternum During a Sneeze Versus During Low-, Moderate-, and High-Intensity Bench Press Resistance Exercise With and Without the Valsalva Maneuver in Healthy Volunteers. (Abstract)

Comparison of Force Exerted on the Sternum During a Sneeze Versus During Low-, Moderate-, and High-Intensity Bench Press Resistance Exercise With and Without the Valsalva Maneuver in Healthy Volunteers. Sternal precautions are intended to prevent complications after median sternotomy, but little data exist to support the consensus recommendations. To better characterize the forces on the sternum that can occur during everyday events, we conducted a prospective nonrandomized study of 41 healthy (...) volunteers that evaluated the force exerted during bench press resistance exercise and while sneezing. A balloon-tipped esophageal catheter, inserted through the subject's nose and advanced into the thoracic cavity, was used to measure the intrathoracic pressure differential during the study activities. After the 1 repetition maximum (1-RM) was assessed, the subject performed the bench press at the following intensities, first with controlled breathing and then with the Valsalva maneuver: 40% of 1-RM

58. Comparison of the use of the Valsalva maneuver and the eutectic mixture of local anesthetics (EMLA(®)) to relieve venipuncture pain: a randomized controlled trial. (Abstract)

Comparison of the use of the Valsalva maneuver and the eutectic mixture of local anesthetics (EMLA(®)) to relieve venipuncture pain: a randomized controlled trial. Intravenous cannulation is a painful and stressful procedure. The objective of this study was to compare the analgesic efficacy of the eutectic mixture of local anesthetics (EMLA(®)) with that of the Valsalva maneuver in adult patients during i.v. cannulation.One hundred ninety-five patients were randomized prospectively to three (...) groups. The dorsum of the nondominant hand was covered with a thick paste of 2.5 g of EMLA(®) cream in the EMLA(®) group (group E) and left for a minimum of 30 min before venipuncture. In the control group (group C), the same procedure was applied except that Vaseline(®) was used instead of the EMLA(®). The Valsalva group (group V) were punctured during a Valsalva maneuver. The patients were placed in the supine position during venipuncture. The patients then scored the amount of pain on cannulation

59. Comparison of the Effect on Right Atrial Pressure of Abdominal Compression Versus the Valsalva Maneuver. (Abstract)

Comparison of the Effect on Right Atrial Pressure of Abdominal Compression Versus the Valsalva Maneuver. When the right atrial pressure (RAP) exceeds the left atrial pressure, right-to-left shunting can occur. Normally, the Valsalva maneuver is used to facilitate elevation of RAP. However, performing the Valsalva maneuver can be problematic in certain situations. The aim of this study was to test the hypothesis that the application of abdominal pressure would increase the pressure within (...) the right atrium compared with the left atrium, making it an adequate alternative to the Valsalva maneuver. Twelve patients were prospectively evaluated during right-sided cardiac catheterization with the application of abdominal pressure as well as a Valsalva maneuver. RAP and left atrial pressure were measured simultaneously. In 11 patients, the mean RAP was lower than the mean pulmonary capillary wedge pressure at baseline. The mean RAP was significantly higher than the mean pulmonary capillary wedge
