"At sign out the circulating nurse confirmed all swab and instrument counts were correct and that the pathology specimen was labelled with the correct patient sticker."

"site marking"

The pre-operative process of clearly marking the intended surgical site with an indelible pen, usually by the operating surgeon, to prevent wrong-site or wrong-side operations

"The anaesthetic nurse documented intraoperative monitoring values every five minutes on the anaesthetic chart throughout the three-hour procedure."

"end-tidal CO2"

The concentration of carbon dioxide measured in exhaled air at the end of each breath, used to confirm correct endotracheal tube placement and assess the adequacy of ventilation and circulation

"A sudden drop in end-tidal CO2 prompted the anaesthetist to suspect pulmonary embolism and immediately review the patient's haemodynamic status."

"mean arterial pressure"

The average arterial pressure throughout one cardiac cycle, calculated from systolic and diastolic blood pressure values; a MAP above 65 mmHg is generally maintained to ensure adequate organ perfusion

"The anaesthetic nurse titrated the vasopressor infusion to maintain a mean arterial pressure above 65 mmHg as requested by the anaesthetic consultant."

"oxygen saturation"

Deliberate measures taken in the perioperative period to prevent or treat hypothermia or, less commonly, targeted hyperthermia, including warm air blankets, fluid warmers, and continuous temperature monitoring

"Temperature management protocols including a forced-air warming blanket and warmed intravenous fluids were applied from anaesthetic induction to prevent perioperative hypothermia."

"post-anaesthesia care unit"

The specialised recovery area, also called the recovery room or PACU, where patients are closely monitored and stabilised immediately after surgery until they meet criteria for ward or ICU transfer

"The patient arrived in the post-anaesthesia care unit with an oxygen mask in place and was transferred to a recovery nurse who commenced one-to-one observation."

"emergence agitation"

A state of confusion, agitation, and combativeness occurring during recovery from general anaesthesia, more common in children and patients who have received certain volatile anaesthetic agents

"The recovery nurse requested the anaesthetist review a patient with emergence agitation who was attempting to remove his endotracheal tube before adequate reversal was achieved."

"Aldrete score"

A standardised scoring system assessing five parameters—activity, respiration, circulation, consciousness, and oxygen saturation—used to determine readiness for discharge from the post-anaesthesia care unit

"The patient achieved an Aldrete score of nine out of ten thirty minutes after surgery, meeting the criteria for transfer to the surgical ward."

"pain assessment"

The systematic evaluation of post-operative pain intensity, character, and location using validated tools such as the numeric rating scale or visual analogue scale to guide analgesic administration

"The recovery nurse performed a pain assessment every fifteen minutes and titrated intravenous morphine to keep the patient's numeric rating scale score below four out of ten."

"post-operative nausea and vomiting"

Nausea and vomiting occurring in the post-operative period, a common complication of general anaesthesia requiring prophylaxis and treatment to prevent discomfort, aspiration, and delayed discharge

"The patient scored high on the Apfel risk assessment for post-operative nausea and vomiting and received prophylactic ondansetron and dexamethasone before emergence."

"oxygen therapy"

The supplemental administration of oxygen via face mask, nasal cannula, or other device in the recovery room to maintain adequate saturation as anaesthetic agents are eliminated and protective reflexes return

"The recovery nurse applied a Hudson mask delivering 40% oxygen therapy and monitored the patient's saturation until it remained stable above 96% on room air."

"shivering"

Involuntary, rhythmic muscle contractions occurring after general or regional anaesthesia, primarily caused by hypothermia and contributing to increased oxygen consumption and patient discomfort

"Persistent shivering was treated with active warming and a small intravenous dose of pethidine while the recovery nurse monitored the patient's core temperature."

"handover to recovery"

The structured verbal communication from the anaesthetist and scrub or circulating nurse to the recovery nurse at the end of a procedure, covering the procedure performed, anaesthetic agents, intraoperative events, and post-operative instructions

"The anaesthetist gave handover to recovery using the SBAR framework, highlighting the patient's history of difficult airway and the need for close respiratory monitoring."

"laparoscopy"

A minimally invasive surgical technique in which a laparoscope is inserted through small abdominal ports to visualise and operate on intra-abdominal structures without a large open incision

"The patient was listed for a diagnostic laparoscopy to investigate chronic pelvic pain after conservative management had failed to identify a cause."

"pneumoperitoneum"

"The circulating nurse connected the CO2 tubing and set the flow rate on the insufflator before insufflation began, confirming correct assembly with the scrub nurse."

"Veress needle"

A spring-loaded needle used to gain initial blind access to the peritoneal cavity for insufflation of CO2, prior to insertion of the first trocar in laparoscopic surgery

"The surgeon used a Veress needle at the umbilicus to commence insufflation after confirming the absence of adhesions from prior abdominal surgery."

"port placement"

The strategic insertion of laparoscopic trocars through the abdominal wall at predetermined anatomical positions to optimise instrument triangulation and visualisation during minimally invasive surgery

"The scrub nurse provided a 10 mm trocar for the umbilical camera port and three 5 mm trocars for the working ports during laparoscopic port placement."

"robotic-assisted surgery"

A form of minimally invasive surgery in which the surgeon operates from a console using magnified three-dimensional vision and robotic instrument arms that translate hand movements into precise actions inside the patient

"The scrub nurse completed a specific training programme for robotic-assisted surgery before being cleared to independently set up the robotic system for urological procedures."

"conversion to open"

The decision during a laparoscopic or robotic procedure to abandon the minimally invasive approach and proceed with an open incision due to complications, poor visualisation, or technical difficulty

"The surgeon announced conversion to open after encountering dense adhesions that obscured the operative field and posed an unacceptable risk of bowel injury."

"clip applicator"

A surgical instrument used laparoscopically or in open surgery to apply titanium or polymer clips across ducts, vessels, or other tubular structures to achieve haemostasis or prevent bile or urine leakage

"The scrub nurse loaded a fresh cartridge into the clip applicator and passed it to the surgeon to secure the cystic duct before division during the cholecystectomy."
