anxiety of pain
Minimal/ no side effects from pain meds
Functionality maintained during and after
intervention
Cheerful and happy

Ask Every Patient:
1. PPG (Personalized
Pain Goal) is
Important
2. Pain at Rest
(Static Pain)
Not of much value
3. Pain on Activity
Dynamic Pain

1. Four grams of Paracetamol / Acetaminophen (IV/PO)/day
2. NSAIDs (Parecoxib, Celecoxib, Diclofenac Na etc.)
3. Pregabalin 75-600mg/day
4. Lidoderm Patch
5. Ketamine
6. Clonidine
7. NERVE BLOCKS
BENZODIAZEPINES ARE NOT ANALGESICS
????. Tramadol along with antiemetic (SR or IR 400mg/day)

Biggest Fears In Treating Pain
Respiratory Depression
Nausea & Vomiting
Addiction
Under Treated Pain
Leads To
“Pseudo Addiction”
Behavior
Most of the fears related to “Opioids”
Severity of Side Effects are dose related
Physical dependency is not addiction
Most Side Effects can be effectively
minimized by “Multimodal approach”
• And by Educating Patients & Providers

PCA Dose
Lockout Interval
(LOI)
Pain down to
patient’s
satisfaction?
Is the pain
relief lasting
till next dose?
Basal Rate
• Needing to press
button many times
• LOI <8min
• Waking up with pain
Encourage
Increase
PCA Dose
by 50 or
100%
Encourage
Decrease
LOI
• >7 day use of opioids
prior to surgery
• Opioid abuse
15
PRN Dose
Dose Interval
Pain down to
patient’s
satisfaction?
Is the pain
relief lasting
till next dose?
ATC, ER or
Patches
• Needing to take all
PRN doses
• PRN dose interval
needing <3 hours
• Waking up with pain
Encourage
Increase
PRN Dose
Encourage
Decrease
Dose
Interval
• >7 day use of opioids
prior to surgery
• Opioid abuse
16
Look for
Over dose
50-60 % of 24 h
consumption as
basal/ ER in
divided doses
60-70% of 24 h
consumption as
PRN doses
In Next Visit
Continue the
same PRN
doses
Increase Basal
/ER by 40-50%
of 24hr PRN
Consumption
Calculate 24 hr

Consumption
