Intraoperative Form

The intraoperative form is where you document the anaesthesia in real time — or fill it in retrospectively. The centrepiece is the live intraoperative timetable.

Month/year and timing

• Month / Year — select the month and year of the procedure. No exact date is stored.
• Start time — click Start Case to stamp the current time automatically, or type it manually (HH:MM format)
• End time — click End Case when the procedure finishes, or enter manually

When Start Case is clicked, a live orange clock bar appears in the timetable and the case status changes to In theatre on the dashboard.

Midnight crossing

If the case crosses midnight (e.g. starts at 23:30, ends at 01:45), click the +1 day button next to the end time to indicate the case ran into the following day.

Anaesthesia technique

Select one or more techniques:

Technique	Description
General Inhalation	Volatile agent as primary technique
General IV (TIVA)	Total intravenous anaesthesia
General Combined	Combination of inhalational and IV
Spinal	Single-shot or continuous spinal
Epidural	Lumbar or thoracic epidural
Combined Spinal-Epidural (CSE)	Combined technique
Peripheral Nerve Block	Any peripheral block
Local Anaesthesia	Infiltration or topical
Sedation	Monitored anaesthesia care

Airway management

Based on the selected technique, the airway section shows relevant options:

• Airway device — Face mask, Oral airway (OPA), Nasal airway (NPA), LMA, Oral ETT, Nasal ETT, Double Lumen Tube (DLT), Endobronchial tube, Surgical airway
• For ETT: tube size (mm) and cuffed/uncuffed
• For DLT: type, side, and size (Fr)
• Airway tools — Direct laryngoscopy, Video laryngoscopy, Fibreoptic bronchoscopy, Bougie, Stylet, Awake intubation, Retrograde intubation
• Cormack–Lehane grade — shown when direct or video laryngoscopy is selected
• Ventilation modes — VCV, PCV, PRVC, PSV, CPAP, BiPAP, etc.

Monitoring

Tick all active monitoring modalities:

• Standard: ECG, SpO₂, NIBP, EtCO₂, Temperature
• Extended: IBP, CVP, PA catheter, TEE, BIS, Entropy, NIRS, SSEP/MEP, TOF/NMT, BGL, ABG
• Other: Urinary catheter, Nasogastric tube

Vascular access

Add each IV line, central line, or epidural catheter:

• Site (peripheral IV, CVC — internal jugular, subclavian, femoral; arterial line — radial, femoral, brachial; epidural)
• Size (G for IV, Fr for central lines)

The intraoperative timetable

The timetable is the visual heart of LOSPOR. It displays everything that happens during the case on a shared timeline, with columns representing 5-minute intervals.

Vital signs

Click a column in the vital signs graph to enter or edit values for that time point:

• Systolic and diastolic blood pressure (displayed as a red line)
• Heart rate (displayed as a green dashed line)
• SpO₂ (displayed as a cyan line)
• EtCO₂ (optional)

The graph updates in real time as you enter data.

AI monitor scan: click the camera icon to upload or photograph your anaesthesia monitor screen. Mistral AI reads the display and extracts visible vital signs values into the entry fields. Review before saving.

Privacy

Monitor images are sent to the configured AI provider for text extraction and are not stored by LOSPOR beyond the request. Avoid uploading images that show patient-identifying information.

Gas management

Record the fresh gas flow and composition:

• FGF — fresh gas flow in L/min
• Carrier gas — Air or N₂O (oxygen is always implicit)
• FiO₂ — inspired oxygen fraction (%)

Drugs (bolus)

Click + Drug in the timetable to log a bolus drug administration:

• Scenario pills for common workflows such as induction, relaxants, local/regional anaesthesia, opioids, vasoactive drugs, PONV/GI, obstetrics, and rescue drugs
• Favourite drugs selected in Settings
• Browse-all search across the canonical drug catalogue
• Dose and unit (mg, mcg, mL, etc.)
• Route-specific controls where applicable; for example IV lidocaine is entered as a dose, while local/neuraxial/peripheral block lidocaine uses concentration and volume
• The bolus appears as a vertical marker at the selected time point
• Each drug event stores the ATC code for the administered drug, enabling research queries by pharmacological class

Infusions

Add a continuous infusion with start time, end time, drug name, rate, and unit. Mobile/PWA uses the same scenario/favourites/browse pattern as bolus drugs. It appears as a hatched bar spanning the infusion duration.

Volatile agents

Record the volatile agent (Sevoflurane, Desflurane, or Isoflurane) used during the case. It appears as a shaded bar across the case duration.

IV fluids

Add fluid boluses or infusions with type (crystalloid, colloid, blood product) and volume. Each appears as a dotted bar in the event strip.

Position

Select the patient position(s) used during the case: Supine, Prone, Lateral, Gynecological, Trendelenburg, Beach chair, Lithotomy, Jackknife, etc.

Premedication

Record the premedication given before the procedure (if different from what was prescribed in the preoperative form).

Fluid balance

At the bottom of the form, a summary of total fluids is automatically calculated from the timetable:

• Crystalloids (mL)
• Colloids (mL)
• Blood products (mL)
• Urine output (mL)

You can also enter these directly.

Complications

Free text field for intraoperative complications. Common complications (hypotension, bradycardia, bronchospasm, etc.) can be selected from a preset list.

Saving

The intraoperative form auto-saves continuously. Vital signs entered in the timetable are stored the same robust way on web and mobile — each 5-minute column is persisted as its own record the moment you finish typing it, so nothing depends on leaving the page open. If the connection drops, changes queue locally and sync automatically when it returns.

When complete, click Save & continue to proceed to the postoperative form.

Mobile

On mobile, the intraoperative form uses the same tab-based layout (Overview, Anaesthesia, Timetable/Chart). The timetable adapts to screen width automatically — all controls remain fully reachable on a phone screen.

The Log tab is designed for fast, thumb-friendly event capture. Vital signs entry opens a dedicated sheet with large input fields. Drug and fluid logging use bottom sheets with preset options and confirmation actions.
