Treatment of Postnatal Drainage (Post-Nasal Drainage)
I believe you are asking about post-nasal drainage rather than "postnatal drainage," as the evidence provided does not address post-nasal drainage treatment. However, I will clarify the most relevant postnatal medical drainage scenarios from the evidence:
If You Mean Post-Nasal Drainage (Upper Airway)
The evidence provided does not contain guidelines for post-nasal drainage treatment. This typically involves:
- Saline nasal irrigation
- Antihistamines for allergic causes
- Decongestants (short-term use)
- Treatment of underlying sinusitis or allergies
If You Mean Postnatal Pleural Drainage (Chest Tubes)
Insertion Pain Management
Local anesthetic infiltration of the skin site before incision should be used routinely unless there is life-threatening instability 1. Slow infiltration reduces pain from lidocaine administration 1. Although no data exists on opioid use before or after chest-tube insertion specifically for pain prevention, this appears to be a reasonable approach based on general principles 1.
Chest Drain Removal
Methohexital provides good pain control without significant respiratory compromise during chest-tube removal in neonates 1. In older children, low-dose morphine and topical lidocaine-prilocaine cream were equally effective 1.
If You Mean Postnatal Bladder Drainage
Postpartum Urinary Retention Management
Early diagnosis and timely intervention with bladder catheterization are necessary to prevent overdistention injury that may damage the detrusor muscle and parasympathetic nerve fibers 2. Continuous urinary catheter drainage is recommended in high-risk situations, such as labor management in women with cardiac disease 1.
Monitoring Requirements
- Postvoid residual volume assessment
- Recognition of covert retention (incomplete emptying) versus overt retention (inability to void) 2
- Intervention before the third postpartum day to prevent persistent retention 2
If You Mean Postnatal Gastric/Intestinal Drainage
Nasogastric or Gastric Tube Drainage
Nasogastric tube drainage is usually uncomfortable, increases aspiration risk, and should only be considered for a limited trial if other measures fail to reduce vomiting 1. This applies primarily to malignant bowel obstruction scenarios 1.
Percutaneous Drainage
For specific conditions like pneumomediastinum, CT-guided percutaneous drainage can be an effective alternative if ultrasound-guided intervention fails 3.
Please clarify if you are asking about post-nasal drainage (upper respiratory) or a specific type of postnatal medical drainage, as the treatment approaches differ substantially.
