简要总结
The investigators reviewed retrospectively the patients that had received septorhinoplasty(SRP). 42 patients were included in the study. Demographic, clinical, surgical, and follow-up data were collected from clinical case notes. The patients that had received sphenopalatine ganglion block(SPGB) before the surgery included in the Block group (n:20) and the patients that had not received SPBG before the surgery included in the Control group (n:22). The postoperative pain(POP) scores, the amount of postoperative rescue analgesics that was used, and the postoperative nausea and vomiting(PONV) scores in the first 24 hours and, mean arterial pressure (MAP), the dose of Remifentanil that was used during the operation were compared between the groups.
详细描述
The patients that had received SRP surgery between January-July 2019, divided into two groups according to the status of receiving SPGB before the surgery. The SPGB was done after the patient anesthetized and performed by the operating surgeon using a transnasal endoscopic approach through the posterior and over the middle turbinate tail in the pterygopalatine fossa. The patient was placed in the supine position with head extension. The prepared solution (4 cc % 4 lidocaine and 1 cc 8 mg dexamethasone) was delivered by a Mucosal Atomization device (LMA MADgic™ Laryngo-Tracheal Mucosal Atomization Device, US). 2,5 cc of the prepared solution was given to each side of the nose. The surgery was started 10 minutes after the application of SPBG, to allow sufficient time for the block to develop.
The open septorhinoplasty technique was done to all patients. The operations were done by the same two otorhinolaryngologists. Control group patients did not receive SPBG and had the surgery only. POP scores were questioned at both groups and postoperative analgesic protocols were the same.
POP was questioned by an anesthesiologist with a numeric rating scale (NRS) (0 = no pain, 10 = most severe pain) at the 30th minute(t1), 1st hour(t2), 4th hour (t3), 12th hour (t4) and 24th hours (t5) and analgesia was managed according to the NRS scores. If the NRS score was > 4, the patient was given Paracetamol 1000mg intravenously, and if the score was still >4 after 30 minutes the patient was given Tramadol 50 mg intravenously. Tramadol was used as rescue analgesia.
PONV was also evaluated. The data of nausea and vomiting were collected by direct questioning by the anesthesiologist at the same times with NRS questioning.
POP scores, the amount of postoperative rescue analgesics that was used, and PONV scores in the first 24 hours were compared between the groups.

结局指标
主要结局
The dose of rescue analgesics
时间窗: 24 hour
If the POP score was \> 4, the patient was given Paracetamol 1000mg intravenously, and if the score was still \>4 after 30 minutes the patient was given Tramadol 50 mg intravenously. The average dose of Paracetamol and Tramadol that were used at the first 24 hours were compared between the groups
Postoperative pain(POP)
时间窗: 24 hour
POP was questioned by an anesthesiologist with a numeric rating scale (NRS) (0 = no pain, 10 = most severe pain) at the 30th minute(min)(t1), 1st hour(h)(t2), 4th hour (t3), 12th hour (t4) and 24th hour (t5).
The dose of Remifentanil
时间窗: 80-240 minute
The dose of Remifentanil that was used during the operation was noted and compared between the groups.
Postoperative nausea and vomiting(PONV)
时间窗: 24 hour
The data of PONV were collected by direct questioning by the anesthesiologist at the same times with POP questioning. If there is 1 min between the episodes of vomiting, each one was considered as separate episodes. Every episode of vomiting was scored as 1 point and total score was calculated after 24 hours.
Mean arterial pressure(MAP)
时间窗: 80-240 minute
MAP was recorded during the operation and the values were compared between the groups.
