• #1 Usefulness of Physical Maneuvers for Prevention of Vasovagal Syncope

  https://www.jstage.jst.go.jp/article/circj/69/9/69_9_1084/_article

  It is known that approximately two-thirds of patients with vasovagal syncope have prodromal symptoms and when these start, physical maneuvers that can increase venous return may abort the syncopal attack. […] The aims of this study were to evaluate the effects of 3 physical maneuvers, squatting, leg-crossing with muscle tensing, and handgrip, on improving hemodynamic status, and to compare the effect of each on aborting or preventing vasovagal syncope. […] Squatting and leg-crossing with muscle tensing improved the hemodynamics of normal subjects as well as those of patients with vasovagal syncope. Squatting and leg-crossing can be used as a simple and effective preventive maneuver in patients with vasovagal syncope.

• #1 Counter pressure maneuvers for syncope prevention: A semi-systematic review and meta-analysis – PubMed

  https://pubmed.ncbi.nlm.nih.gov/36312294/

  Physical counter pressure maneuvers (CPM) are movements that are recommended to delay or prevent syncope (fainting) by recruiting the skeletal muscle pump to augment cardiovascular control. […] CPM improved standing systolic blood pressure (+ 14.8 0.6 mmHg,p0.001) and heart rate (+ 1.4 0.5 bpm,p= 0.006), however, responses of total peripheral resistance, stroke volume, or cerebral blood flow were not widely documented. […] Physical CPM were successful in improving syncopal symptoms and producing cardiovascular responses that may bolster against syncope; however, practical limitations may restrict applicability for use in daily living.

  Initial measures include performing physical counter-pressure maneuvers (class IIa), increasing salt and fluid intake (class IIb) in the absence of contraindications, and, in selected patients, reducing or withdrawing hypotensive medications when appropriate (class IIb). […] […] Physical counter-pressure maneuvers are recommended for patients whose syncopal episodes have a sufficiently long prodromal period. Maneuvers include the following: Leg crossing: crossing the legs while tensing leg, abdominal, and buttock muscles; Handgrip: maximally contracting a rubber ball or other object in the dominant hand; Squatting; Limb or abdominal contractions; Arm tensing: contracting both arms by gripping one hand with the other and abducting both arms. […] […] The effectiveness of counter-pressure maneuvers was studied by van Dijk et al in a multicenter prospective randomized clinical trial that included 223 patients with recurrent vasovagal syncope associated with prodromal symptoms. They concluded that these maneuvers decreased the recurrence of syncopal episodes, with a relative risk reduction of 0.36 (95% confidence interval 0.110.53, P .005) and were low-cost and risk-free.

  The evidence for increasing salt and fluid intake for patients with vasovagal syncope is limited. But in the absence of a contraindication such as hypertension, renal disease, or heart failure, it may be reasonable to encourage the ingestion of 2 L to 3 L of fluid per day and a total of 6 g to 9 g of salt per day (around 1 to 2 heaping teaspoons of salt). […] […] In patients who continue to have syncopal episodes despite adequate use of first-line measures, medical therapy can be considered. Unfortunately, evidence supporting drug therapy for recurrent syncope is limited. Options include midodrine (class IIa), fludrocortisone (class IIb), beta-blockers (class IIb), and selective serotonin reuptake inhibitors (class IIb).
