Invasive continuous arterial blood pressure monitoring is useful in that it provides beat-to-beat measurements and also allows sampling of arterial blood for analysis, but securing an arterial cannula should not delay prompt management of the airway.
Instrumentation and Operating Theater Set up in Minimally Invasive Cardiac Surgery

Once the cannulas are correctly positioned they are secured to the skin by using silk sutures. Most of the time the arterial cannula can be secured by needle and suture technique, and the venous cannula with sharp clips. In particular multistage venous cannulas need to be adjusted preoperatively (Figure 4.12).
Regional Therapy of Liver Metastases: A Surgeon’s View

Morbidity related to the insertion of the arterial cannula was restricted to one wound infection and one deep venous thrombosis. All patients developed nausea during treatment sessions immediately after the administration of DSM. This was short-lived, lasting only 30 to 60 min. Occasional pain or discomfort was also experienced, but this was also of similar duration. Importantly, there were no systemic side effects, such as alopecia or hematological toxicities.

In the operating room, patients were connected to the standard monitoring system for measuring heart rate, blood pressure, o2 saturation, and temperature. Vascular access was in the form of a suitable size (20 G) arterial cannula; for sampling and invasive blood pressure monitoring, two large-bore (14–18 G) peripheral venous cannulas, a percutaneous sheath (6 or 7 F) as well as a central venous catheter. General anesthesia was induced in the two groups using Fentanyl 2 μg/kg IV, Propofol 2 mg/kg IV, atracurium 0.5 mg/kg IV followed by endotracheal intubation and maintenance with a combination of air and oxygen 50% with isoflurane. Adjustments of mechanical ventilation were made targeting end-tidal CO2 (35–40 mmHg). Albumin 4% in Ringer acetate was used to maintain central venous pressure (CVP) less than 5 mmHg in the dissection phase and >5 mmHg. Afterward, packed red blood cells were transfused with a target hematocrit of 25% and Hb of 8 g/dL. Data were collected as regards systemic hemodynamics variables such as diastolic and systolic blood pressure, and heart rate. Additionally, the variables of acid base balance in the form of lactate and base deficit. Other variables examined included the blood product requirements, hourly urine output and total norepinephrine requirements.

Eligibility of the study: Patients could be initiated on the protocol if they had fulfilled the above criteria and their first arterial line (index arterial line) inserted during their first day ICU admission was complicated by documented thrombosis or arterial line failure. Arterial line failure included; 1) severe arterial waveform dampening that did not improve with flushing or repositioning; 2) Inability to withdraw blood from the catheter, and/or; 3) Catheter malfunction requiring replacement with documented thrombosis on bedside ultrasound of the vessel [10]. They should have a peripheral artery cannulation with a suitable arterial cannula and a functional arterial line established after insertion. The duration of enrolment and start of Systemic Anticoagulation protocol implementation are as explained before.

For intra-nuclear administration in RVLM, each animal was placed in prone with the was mounted in a stereotaxic instrument (RWD, China) to ensure that the bregma and lambda were positioned on the same horizontal plane. RVLM microinjections were performed with a glass micropipette (tip diameter is 50–70 microns) by using the following coordinates: 3.7–4.0 mm caudal to lambdoid suture, 2 mm lateral to the midline, and 8.0 mm ventral to the surface of the dura (28). The amount of microinjection drug was glutamate receptor antagonist (Dizocilpine 20 pmoles & CNQX 150 pmoles) or GABA receptor antagonist (Bicuculline 5 pmoles) (MCE, China), and the volume was controlled at 1 μL/side. After each microinjection, the micropipette was left in place for approximately 3 minutes (23,29). The rats were anesthetized with urethane (1–1.5 g/kg iv) at supplemental doses as required (0.1–0.3 g/kg iv). The right femoral artery was cannulated using polyethylene catheters filled with heparinized saline (50 U/mL) (30). The distal end of the arterial cannula was attached to a pressure transducer to directly monitor the blood pressure (BP). Systolic blood pressure (SBP) and heart rate (HR) were simultaneously measured.
