Understanding arterial pressure waveforms
their relation to the cardiac cycle
the difference in waveforms recorded from different body
sites
The arterial pulse is the result of a wave of vascular distention,
initiated by the impact of the stroke volume ejected into
a closed system with every heartbeat. The forward-propagating
pressure wave has both a fast-moving (10m/sec) and slower
(0, 5m/sec) component.5 The wave is reflected back mostly by
the arteriole, which provides the majority of peripheral vascular
resistance.6 Peak aortic blood flow acceleration produces
the initial rise of the pressure pulse, whereas the ejection ..

TL;DR: Melatonin (3 mg) can be successfully used as premedication for laparoscopic cholecystectomy, especially for day case surgery, and a better recovery profile as assessed by sedation and memory.
Abstract: Background: There are only a few studies involving the use of melatonin for premedication for anaesthesia. The goal of our study was to compare the effects of melatonin and midazolam administered a...

TL;DR: The incidence of postoperative pain is high as expected at a Western Cape referral hospital, and at least one low-cost analgesic modality is currently underutilised.
Abstract: Background: Postoperative pain is poorly studied in developing countries. At a Western Cape referral hospital, it was aimed to determine the incidence of acute postoperative pain, to identify populations associated with a higher risk thereof (in order to guide resource allocation) and to investigate whether inexpensive analgesic modalities are currently utilised maximally.Methods: Patients completed visual analogue scales 24 h after surgery for pain immediately after surgery, maximum pain since surgery and current pain. The incidence of moderate or severe pain and median pain scores were calculated for each scale and for different patient populations. Post hoc logistic regression was performed. Morphine prescriptions were compared with the actual administration thereof.Results: Of 1 231 patients, 62% indicated their maximum pain as moderate or severe. Procedures with the highest incidences were caesarean section and lower limb orthopaedic surgery (> 80%). Younger age, female gender, emergency surgery, and...

TL;DR: The purpose of this review is to discuss dexmedetomidine in terms of its pharmacokinetics and pharmacodynamics, and to focus on its various clinical applications.
Abstract: Dexmedetomidine is a highly selective and potent alpha2-adrenoreceptor (AR) agonist offering dosedependent sedation, anxiolysis and analgesia. It is a relatively new drug, approved for sedation for up to 24 hours in mechanically ventilated post-cardiac surgery patients. Yet, because of its unique drug profile, it has been increasingly studied and used in various clinical settings, albeit off label, with promising results. The purpose of this review is to discuss dexmedetomidine in terms of its pharmacokinetics and pharmacodynamics, and to focus on its various clinical applications. A PubMed search, using the keyword “dexmedetomidine”, identified approximately 1,000 articles, the earliest being animal studies published in 1988.

TL;DR: The reasons for this chronic post-surgical pain are discussed in this presentation, as are possible preventative strategies.
Abstract: Why some patients develop chronic pain after an acutely painful event remains an enigma. For example, over 90% of the population will experience acute back pain at some time in their lives. In most cases this resolves but, in a few, it does not, even though these patinets have radiologic pathology similar to those in whom the pain does improve.
Similarly, there are few people who escape the hands of the
surgeon. What is becoming increasingly apparent is that those who do experience the sharp end of the scalpel frequently experience persistent pain as a result of the damage caused by this instrument.
The reasons for this chronic post-surgical pain are discussed in this presentation, as are possible preventative strategies.
