Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Summary

Ultrasound-guided suprazygomatic maxillary (SZM) nerve blocks reduce intraoperative opioid use and post-anesthesia care unit (PACU) stay for nasal surgery patients. This alternative pain management strategy enhances recovery after surgery (ERAS) protocols effectively.

Area of Science:

Anesthesiology
Pain Management
Surgical Innovation

Background:

Growing interest in non-opioid pain management strategies.
Enhanced Recovery After Surgery (ERAS) protocols emphasize multimodal analgesia.
Need for effective adjuncts to traditional pain management in nasal surgery.

Purpose of the Study:

To describe and evaluate ultrasound-guided suprazygomatic maxillary (SZM) nerve blocks.
To assess SZM blocks as an adjunct for postoperative pain management in nasal surgery.
To analyze the impact of SZM blocks on intraoperative anesthetic/opioid use and PACU stay.

Main Methods:

Retrospective, multicenter analysis of 64 patients undergoing functional or cosmetic nasal surgery.
Comparison between patients receiving SZM blocks and those receiving standard local anesthesia.
Evaluation of intraoperative medication use, postoperative pain scores, and PACU length.

Main Results:

SZM blocks significantly reduced intraoperative pain medication, including hydromorphone (p=0.02).
A significant reduction in post-anesthesia care unit (PACU) stay was observed at one institution (p=0.016).
SZM blocks demonstrated effectiveness in reducing intraoperative opioid requirements.

Conclusions:

Ultrasound-guided SZM nerve blocks are a simple and effective local anesthetic technique.
SZM blocks are associated with decreased intraoperative opioid use in nasal surgery.
This technique contributes to reduced PACU stay, supporting enhanced recovery protocols.
