Management of Pain Associated with the Sterling Maneuver
Pain associated with the Sterling maneuver should be managed using a multimodal approach that includes both pharmacological and non-pharmacological interventions, with careful consideration of the patient's specific pain characteristics and risk factors for persistent pain.
Understanding the Sterling Maneuver and Associated Pain
The Sterling maneuver (also known as Valsalva maneuver) involves increased intrathoracic pressure that causes rapid changes in preload and afterload stress. During this maneuver:
- Venous return to the heart decreases
- Peripheral venous pressures increase
- Systolic and pulse pressures fall
- Mean arterial pressure remains near or elevated above control levels 1
Pain during this maneuver may be related to these physiological changes and can be particularly concerning in certain patient populations.
Initial Assessment
Before implementing pain management strategies, assess:
- Pain intensity using a validated pain scale
- Duration and character of pain
- Precipitating and alleviating factors
- Impact on daily activities and function
- Psychosocial factors that may influence pain perception 2
Risk Stratification
Identify patients at higher risk of developing persistent pain:
- Those with pre-existing pain conditions
- Psychological factors (anxiety, depression, catastrophizing)
- Previous negative experiences with the procedure
- Significant impact on function or work 2
Pain Management Approach
Pharmacological Interventions
Basic Level Management:
- Local anesthetics for wound infiltration if applicable
- NSAIDs (oral, rectal, or IV)
- Paracetamol/acetaminophen (oral, rectal, or IV) 2
Intermediate Level Management (if basic management insufficient):
- Continue NSAIDs and paracetamol
- Add intravenous fentanyl or other appropriate opioid in divided doses 2
Advanced Level Management (for severe or refractory pain):
Non-Pharmacological Interventions
- Patient education about the procedure and expected sensations
- Relaxation techniques and breathing exercises
- Cognitive behavioral approaches
- Physical modalities (heat, cold) where appropriate 2
Monitoring and Follow-up
Use the "four A's" approach to monitor treatment effectiveness:
- Analgesia (pain relief)
- Activities of daily living (functional improvement)
- Adverse effects (side effects monitoring)
- Aberrant drug-taking (if opioids are prescribed) 2
For patients with persistent pain:
- Reassess within 6 months
- Consider referral to pain specialist if no improvement within 8-12 weeks
- Shorten timeframe for specialist referral if pain significantly impacts work or function 2
Special Considerations
Procedure-Related Pain Management
For pain specifically related to procedures involving the Sterling maneuver:
- Provide written instructions and education before the procedure
- Consider pre-procedural anxiolytics if anxiety is significant
- Use local anesthetics with sufficient time for effectiveness
- Implement non-pharmacological interventions to promote a sense of control 2
Movement Considerations
Pain can alter movement patterns, which may perpetuate the pain cycle. Consider:
- Appropriate physical activity that doesn't exacerbate pain
- Attention to movement quality, not just quantity
- Gradual return to normal activities 4
Pitfalls and Caveats
- Avoid overreliance on opioids due to potential side effects and dependence
- Don't dismiss psychosocial factors that may influence pain perception
- Avoid prolonged investigations that delay appropriate management
- Be aware that pain perception may be influenced by the salience network in the brain, affecting how patients report and experience pain 5
- Remember that pain can influence motor preparation in the brain, potentially affecting movement patterns 6
By implementing this structured approach to managing pain associated with the Sterling maneuver, clinicians can effectively address both the physiological and psychological aspects of pain, improving patient outcomes and quality of life.
