Title: Total Intravenous Versus Inhaled Anesthesia in Endoscopic Sinus Surgery for High-Grade Paranasal Disease
Brief Summary: Utilization of total intravenous anesthesia (TIVA) has been proposed as a method to improve visualization during endoscopic sinus surgery (ESS), largely due to its physiologic decrease in cardiac output without the peripheral smooth muscle relaxation and resultant vasodilation associated with inhaled anesthetics. This may be especially important in cases of advanced inflammatory sinus disease, when visualization may be most compromised. The goal of this study is to improve clinical practice paradigms by evaluating the use of TIVA versus inhaled anesthetic for maintenance of anesthesia in ESS for advanced paranasal sinus disease.


Options:
A: Inclusion Criteria:

* Patients undergoing endoscopic sinus surgery
* Advanced inflammatory sinus disease, defined as allergic fungal sinusitis, chronic rhinosinusitis with nasal polyposis, chronic rhinosinusitis with eosinophilia, or rhinosinusitis with pan-sinus opacification (Lund-Mackay score \>12).

Exclusion Criteria:

* Noninflammatory sinonasal disease
* Disease extending through the skull base or orbital wall
* American Society of Anesthesiologists Preoperative Health Status \>II
* Known non-pharmacologic coagulopathy (platelet \< 50000/mL, international normalized ratio \> 1.2)
* Preoperative anticoagulants within 7 days of surgery
* Allergy to one of the study medications
* Age under 18 years
* Non-English-speaking
B: Inclusion Criteria:

All trauma patients with ongoing significant haemorrhage (systolic blood pressure less than 90 mmHg and/or heart rate more than 110 beats per minute), or who are considered to be at risk of significant haemorrhage, and are within 8 hours of the injury, are eligible for trial entry if they appear to be at least 16 years old. Although entry is allowed up to 8 hours from injury, the earlier that patients can be treated the better.

Exclusion Criteria:

The fundamental eligibility criterion is the responsible doctor's 'uncertainty' as to whether or not to use an antifibrinolytic agent in a particular adult with traumatic haemorrhage. Patients for whom the responsible doctor considers there is a clear indication for antifibrinolytic therapy should not be randomised. Likewise, patients for whom there is considered to be a clear contraindication to antifibrinolytic therapy (such as, perhaps, those who have clinical evidence of a thrombotic disseminated intravascular coagulation) should not be randomised. Where the responsible doctor is substantially uncertain as to whether or not to use an antifibrinolytic, all these patients are eligible for randomisation and should be considered for the trial. There are no other pre-specified exclusion criteria
C: Inclusion Criteria:

* patients underwent endoscopic sinus surgery

Exclusion Criteria:

* patients with uncontrolled hypertension or coronary artery disease, anaemia, end stage renal failure, liver cirrhosis, patients with coagulopathy or receiving drugs influencing blood coagulation, cerebrovascular thrombosis or history of thrombotic events, pregnancy, known sensitivity to any of the study drug and patients' refusal to participate in the study.
D: Inclusion Criteria:

Patients must be diagnosed with either:

1. Chronic rhinosinusitis with polyposis (CRSwP) or
2. Chronic hyperplastic sinusitis. Patients must have an ASA classification of I or II and must be undergoing bilateral FESS as treatment for one of the above diagnoses.

Exclusion Criteria:

1. Hypertension (treated or untreated)
2. Thrombotic diathesis
3. Vascular disease, risk factors for vascular disease,
4. Colorblindness
5. Renal failure
6. Pregnancy
