Two completely different generations of Blackpool tram here... representing the 'streamliner' generation is Balloon tramcar 706 'Princess Alice' - built in 1934/35, this was one of 27 English Electric Balloons built, and was originally closed top until 1980 after an accident with 705 - and can carry 84 seated passengers plus 10 standees.

Alongside 706 is the modern day equivalent from 2012, a Bombardier Flexity Swift 2, number 013... ordered in 2009 by Blackpool Council, this is one of 16 built, of an order costing £33million, and is currently the only tram of this type in the world. These are wider than the older trams (2.65m), but have only 74 seats plus 148 standing spaces. They can go at up to 43.5mph and are 32.25m long.

It is quite possible that this investment in new trams saved the Blackpool Tramway, the oldest electric tram system in the world. The old fleet of Balloons and Railcoaches (which is what they all were, even if outside they had been modernised) were costing a lot to maintain and were quite slow in comparison to the number 1 bus service which runs parallel to the tramway through its length. The 16 Flexities run a year-round service at a frequency of 4 trams per hour along the full length of the route, and have faster top speed and acceleration than the old trams, so giving the tramway the edge over the bus service. These trams are also 100% wheelchair accessible, and are fitted with audio visual passenger information systems (although they are quite repetitive... "Mind the doors please... hold tight please"). These trams are easy and cheaper to maintain than the older trams, so a more reliable service can be run. Without this, it is likely the tramway would have wound up and closed down due to lack of funds to run it....

During bank holiday weekends, such as here on Easter Weekend 2013, some members of the restored Heritage Fleet come out to provide special limited stop journeys in addition to the service offered by the Flexities - some of these special services have made unscheduled extensions to Fleetwood at the request of the passengers. Different ticket types are available, but I went for a very reasonable "all mode" type ticket which allowed me unlimited day travel by heritage tram, flexity tram, and bus, throughout the whole Blackpool Transport network, all for just £10. The limited stop services the heritage fleet run mean they keep up with the Flexities (in fact whilst I was there, they either gained ground on them if in front or caught up with them if behind and had to wait until the Flexities moved from the stop).

Contrast, not just black & white.... This small waterflower, blossoms just above the waterlevel....so also wet & dry.

Contrast

The main component of CT/X-ray Contrast Media is iodine. The Iodinated Contrast Media is a colorless, transparent, slightly viscous liquid. At present, the CT contrast agents can be mainly divided into ionic and non-ionic, according to the osmotic pressure can be divided into hypertonic, isotonic and hypotonic. Currently, non-ionic, isotonic or hypotonic Contrast Media are used clinically. When the CT contrast medium is injected, 97% of the contrast media can be directly excreted from the kidneys within 1 day.

Reasonable Use of Iodinated Contrast Agents

Evaluate patient benefits/risks before use

History of allergies: Patients who have previously experienced moderate to severe anaphylactoid reactions to iodinated contrast agents or patients with a history of allergies requiring treatment are at an increased risk of having an allergic reaction to CT dye.

Kidney function: iodinated contrast agents can cause acute kidney injury, and patients should be evaluated for related risks before the surgery.

Combination medication: drugs that may increase the risk of adverse reactions to iodinated contrast agents: neuroleptics and antidepressants, interleukin-2, beta-blockers, metformin.

Situations where iodinated contrast agents should be used with caution: lung and heart diseases, catecholamine secreting tumours, pregnant and lactating women, myeloma and macroglobulinemia, myasthenia gravis, homocystinuria.

Contraindication: uncured patients with hyperthyroidism.

Dose limit for iodinated contrast agents

On the premise of satisfying imaging/diagnosis, the minimum dose of iodinated contrast agents should be used.

For low-risk patients, the total dose of types of contrast agents had better be controlled within 300 ~ 400 ml.

Maximum dose of iodinated radiocontrast dye

Method I *: 5 ml × body weight (kg)/serum creatinine (mg/dl) (not more than 300 ml) [refer to Cigarroa calculation formula]

Method II: 3.7 times creatinine clearance [according to 2011 ACCF/AHAUA/NSTEMI Treatment Guidelines]

For those with severe renal insufficiency, try to choose an imaging method that does not require iodine-based contrast agents or a non-imaging method that can provide sufficient diagnostic information.

Avoid repeated use of the diagnostic dose of an iodinated contrast agent in a short period of time. If repeated use is indeed necessary, it is recommended that the interval between two MRI contrast agent applications be ≥14 days.

Other precautions for the use of iodinated contrast agents

Preheating: Before using an iodinated contrast agent, it is recommended to heat the contrast agent to 37 °C and place it in a thermostat.

Hydration: It is recommended to hydrate patients within 6 to 12 hours before using an iodinated contrast agent to within 24 hours after use. Hydration method: Intra-arterial drug users are advised to receive intravenous rehydration and oral rehydration concomitantly, and oral rehydration is recommended for intravenous drug users.

Stay and observation: After the injection of the iodine-based contrast media, the patient needs to stay and be observed for 30 minutes before leaving the examination room.

Establish an emergency channel: Establish an emergency rapid support mechanism for the rescue of adverse reactions caused by iodinated contrast agents with the emergency room or other clinical related departments to ensure that after an adverse reaction occurs, clinicians can promptly rush to the rescue scene for rescue if necessary.

Prevention and Management of Vascular Extravasation of Iodinated Contrast Agents

Prevention

Choose appropriate blood vessels for venipuncture and operate carefully; when using a high-pressure syringe, choose a puncture needle and catheter that match the injection flow rate; properly fix the puncture needle; communicate with the patient and get cooperation.

Management

Mild extravasation: Most injuries are minor and need no treatment. However, the patient should be instructed to keep observing. If the extravasation worsens, the patient should seek medical attention in time. For individuals with significant pain, common cold and hydropathic compresses can be given locally.

Moderate and severe extravasation: ① raise the affected limb to promote blood return. ② Use 50% magnesium sulfate moisturizing cold compress in the beginning, and after 24-hours change to magnesium sulfate moisturizing hot compress, or use mucopolysaccharide ointment for topical application, or use 0.05% dexamethasone for local hydropathic compress. ③ Those with severe contrast agent extravasation should be given oral dexamethasone 5 mg/time tid for 3 consecutive days on the basis of topical drug use. ④ If necessary, consult a clinician for medication.
