简要总结
This study aimed to show the effect of sphinopalatine ganglion blockade on surgical field, hemodynamics and postoperative pain in FEES operation.
详细描述
Functional endoscopic sinus surgery (FESS) is a minimally invasive, effective surgical technique that is commonly used to treat chronic rhino sinusitis and nasal polyposis.
Intra-operative bleeding obscures the surgical view and increases the likelihood of iatrogenic complications. There are many factors that can affect the amount of bleeding experienced during surgery including both patient and surgical factors. These include severe forms of chronic sinusitis with nasal polyposis which is associated with increased vascularity, use of anticoagulant therapy, bleeding disorders, active infection, vascular tumor on the surgical site and revision surgery may affect bleeding on surgical site.
Sphenopalatine ganglion (SPG) is the main sensory innervation to the nasal mucosa.
The Sphenopalatine ganglion block (SPGB) is one of the regional anesthetic techniques that were used effectively before removal of nasal packing and in patients undergoing endoscopic sinus surgery under general anaesthesia to control bleeding or for postoperative analgesia

结局指标
主要结局
surgical field quality
时间窗: during the surgery
bloodless clear surgical field will be assessed for each side by surgeon using five categories categories. 1. = uncontrolled bleeding. 2. = severe bleeding, surgical conditions distorted immediately afterwards suctioning. 3. = moderate bleeding, frequent suctioning required, visibility of the surgical field is moderate. 4. = slight bleeding, occasional suctioning required, visibility of the surgical field is good. 5. = no bleeding almost bloodless surgical field.
次要结局
- Postoperative pain(immediately after the surgery and 12 , 24 hours after the surgery)
- postoperative infection(after the surgery( up to 24 hours))
- postoperative epistaxis(after the surgery( up to 24 hours))
- blood pressure(during the surgery and after the surgery( up to 24 hours))
- heart rate(during the surgery and after the surgery( up to 24 hours))
