STARGATE: International obServational sTudy on AiRway manaGement in operAting Room and Non-operaTing Room anaEsthesia
Study Details
Study Description
Brief Summary
According to WHO, more than 230 million major surgical procedures are carried out under general anaesthesia each year worldwide. Despite important technological advances, airway management remains a major challenge in anaesthesiology. Data from large perspective studies on current incidence of major peri-intubation adverse events are lacking in the anaesthesia setting, especially on outcomes such as peri-intubation cardiovascular collapse, severe hypoxemia, and cardiac arrest. These events are more common in case of difficulties with airway management so that first pass intubation failure significantly increase the risks. Moreover, it has been documented that even transient hypotension during general anaesthesia, may have long-term consequences and may be associated with a worse outcome in patients undergoing non-cardiac surgery. The primary aim of the study is to assess the current incidence of major peri-intubation adverse events during anaesthesia in patients undergoing elective or emergency surgery and in the setting of nonoperating room anesthesia. The secondary aim is to assess the current practice of airway management during anesthesia worldwide.
STARGATE Study will be a large international observational study recruiting all consecutive adult (≥ 18 years old) patients undergoing general anesthesia in operating room and outside operating room. Primary outcome will be a composite of cardiovascular collapse, cardiac arrest and severe hypoxemia.

Study design: International, multicenter, prospective cohort study
Inclusion criteria: We will include all adult (≥ 18 years old) patients undergoing intubation for general anaesthesia in operating room (OR) or non-operating room anaesthesia (NORA).
Exclusion criteria: Airway management during cardiopulmonary resuscitation; critically ill patients undergoing intubation due to their underlying clinical condition.
Primary outcome: At least one of the following major peri-intubation adverse events occurring within 30 minutes from intubation or up to surgical incision: severe hypoxia, cardiovascular collapse, cardiac arrest.
Study duration: All centers will select a 7-day period of observation and they will enroll all consecutive patients meeting study criteria.
Collected data: We will collect the following information:
-
Informed consent and admission data
-
Demographic and clinical characteristics
-
Type of procedure (time, setting, type of surgery, elective or emergency
-
Airway evaluation (anticipated difficult airway management)
-
Monitoring applied during the procedure

Elective method for laryngoscopy
-
Operator's characteristics
-
Method used for the second (and following) attempt
-
Method used for adequate tube placement confirmation
-
Duration of laryngoscopy
-
Outcome of endotracheal intubation (total number of attempts, laryngoscopy view, minimum SpO2 during laryngoscopy, need for LMA)
-
Intubation-related complications (severe cardiovascular collapse, severe and mild hypoxemia, cardiac arrest, airway injury or any bleeding, aspiration of gastric contents, dental injury, emergency front of neck airway (FONA), cannot intubate cannot oxygenate scenario (CICO), unplanned need for ICU secondary to airway management complications)
-
Extubation procedure.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Patients undergoing anesthesia in operating room and outside operating room Patients undergoing elective or emergency tracheal intubation to receive general anesthesia for surgery in operating room or outside operating room (e.g. endoscopy and radiology unit, cardiology lab cath) |
Procedure: Tracheal intubation
Advanced airway management with tracheal intubation performed after induction with hypnotic and/or opioid drugs and laryngoscopy
|
Outcome Measures
Primary Outcome Measures
- Major peri-intubation adverse event [30 minutes from induction]
Defined as at least one of the following events: Cardiovascular collapse (at least one of the following): Systolic arterial pressure < 65 mmHg Systolic arterial pressure < 90 mmHg for > 15 minutes New need of vasopressors and/or fluid load > 15 ml/kg to maintain the target blood pressure Cardiac arrest Severe hypoxemia (SpO2 < 80%)
Secondary Outcome Measures
- Minor peri-intubation adverse events [30 minutes from induction]
At least one of the following: Moderate hypoxia (SpO2 < 93%) Airway injury Clinically relevant bleeding Oral aspiration of gastric contents Dental injury
- Difficult facemask ventilation [30 minutes from induction]
Impossibility to provide adequate ventilation because of one or more of the following problems: inadequate mask seal, excessive gas leak, or excessive resistance to the ingress or egress of gas
- First pass success rate [30 minutes from induction]
Incidence of successful intubation after a single attempt of laryngoscopy
Other Outcome Measures
- Emergency front of neck access (eFONA) [30 minutes from induction]
Emergency need for invasive access to the patient's neck to provide adequate oxygenation (e.g. cricothyroidotomy, percutaneous tracheostomy, surgical tracheostomy).
- Cannot intubate cannot oxygenate (CICO) [30 minutes from induction]
Impossibility to achieve a successful tracheal intubation and adequate patient's oxygenation
- Unplanned need for ICU secondary to airway management complications [24 hours from induction]
Unplanned admission to ICU after an airway-related complication or prolonged/difficult instrumentation
- In-hospital mortality [28 days from induction]
Death during the same hospital admission
