Safety of ketamine in Australia ventilated intensive care unit patients by doctor Tom Niccol

Safety of ketamine in Australia mechanically ventilated intensive care unit patients with Dr. Tom Niccol: In Australian and New Zealand, mechanically ventilated patients account for about 35% of all adult patients admitted to the intensive care unit (ICU). In addition to treating the primary illness, international clinical practice guidelines emphasise five critical domains in the management of ventilated patients. These are pain assessment and management, sedation and agitation prevention, delirium assessment and treatment, rehabilitation and mobilisation, and minimising sleep disruption. See additional details on https://www.theguardian.com/advertiser-content/medecins-sans-frontieres-2019/medical-care-without-limits-the-hospital-in-a-swamp.

Mechanically ventilated patients account for about one-third of all admissions to the intensive care unit (ICU). Ketamine has been conditionally recommended to aid with analgesia in such patients, with low quality of evidence available to support this recommendation. We aimed to perform a narrative scoping review of the current knowledge of the use of ketamine, with a specific focus on mechanically ventilated ICU patients.

Another CNS effect of ketamine is NMDA receptor blockade of the dorsal horn cells of the spinal cord. These are thought to be important in the pain “wind up” phenomenon, leading to opioid desensitisation, and increased acute and chronic pain. Ketamine boluses of 0.15 mg/kg have been shown attenuate this process. Estimates of the rates of chronic pain in the year after ICU admission are 14–77%, 28 and it is unknown what role ketamine may have in reducing this critical illness complication.

Methods: We searched MEDLINE and EMBASE for relevant articles. Bibliographies of retrieved articles were examined for references of potential relevance. We included studies that described the use of ketamine for postoperative and emergency department management of pain and in the critically unwell, mechanically ventilated population.

A wide range of surgeries were included. Ten studies used only S-ketamine and one study used only R-ketamine. The rest of the studies used racemic ketamine at predominantly bolus doses of 0.25–1 mg/kg and infusions of 2–5 μg/kg/min (0.12–0.3 mg/kg/h). Most studies had less than 50 patients in each arm. Ketamine infusion reduced morphine equivalents by 8 mg at 24 hours and by 13 mg at 48 hours with associated decreased pain scores. Pooled CNS adverse events included hallucinations, dizziness, confusion, drowsiness, sedation, nightmares, and visual disturbances. There was no statistical difference in pooled events when ketamine was compared with placebo (5.2% v 4.2%; risk ratio, 1.17; 95% CI, 0.95–1.43). The authors concluded that “perioperative intravenous ketamine probably reduces postoperative analgesic consumption and pain intensity. CNS adverse events were little different with ketamine or control”.

Results: There are few randomised controlled trials evaluating ketamine’s utility in the ICU. The evidence is predominantly retrospective and observational in nature and the results are heterogeneous. Available evidence is summarised in a descriptive manner, with a division made between high dose and low dose ketamine. Ketamine’s pharmacology and use as an analgesic agent outside of the ICU is briefly discussed, followed by evidence for use in the ICU setting, with particular emphasis on analgesia, sedation and intubation. Finally, data on adverse effects including delirium, coma, haemodynamic adverse effects, raised intracranial pressure, hypersalivation and laryngospasm are presented.

Raised intracranial pressure: Early observational studies suggested ketamine was associated with raised ICP in patients with space-occupying lesions 71, 72 and there were concerns with its use in traumatic and non-traumatic brain injury. However, to address these concerns, there have been several small randomised controlled trials of ketamine combined with midazolam versus narcotic combined with midazolam. Low dose. There are no studies using low dose ketamine to study its effects on raised ICP.

Conclusions: Ketamine is used in mechanically ventilated ICU patients with several potentially positive clinical effects. However, it has a significant side effect profile, which may limit its use in these patients. The role of low dose ketamine infusion in mechanically ventilated ICU patients is not well studied and requires investigation in high quality, prospective randomised trials.

Hunan Rika Electronic Tech Co.,Ltd is a privately held sensor manufacturer and solution provider of environmental & weather monitoring for 10+ years. In addition to weather station, we offer a complete line of weather instruments including anemometers, barometers, thermometers, rain gauges, soil sensors, water sensors and accessories. Rika also develops bespoke products to meet specific customer requirements. Our weather station and weather sensors are wided used around the world in a broad range of monitoring applications, from verifying the performance of green buildings and renewable energy systems to agricultural and coastal research.

Ambient instruments and equipment traditionally used for atmospheric environmental quality monitoring are generally large-scale analytical instruments. The equipment is cumbersome and expensive, which is not conducive to the wide deployment of monitoring points, thus restricting the effective monitoring and treatment of the atmospheric environment. The ambient sensor effectively solves the problems of existing analytical instruments. Atmospheric environmental monitoring sensors include air temperature, humidity, air pressure, dust, visibility, CO2, CO, SO2, O3, NH3 and other sensors, which are widely used in industrial and agricultural production and air quality monitoring.

The automatic weather meter simultaneously measures atmospheric temperature, atmospheric humidity, air pressure, wind speed, wind direction, solar radiation, illuminance/ultraviolet rays, dust concentration and precipitation. The temperature, humidity and air pressure sensors are placed inside the radiation shield. The wind speed and direction of the ultrasonic principle. Rainfall detection by 24G radar can quickly detect rainfall and intensity. The system can be installed with a built-in GPS global positioning module and electronic compass, which can well indicate latitude, longitude and relative speed, and can calculate real and virtual wind speed and direction. It is especially suitable for installation on motion vectors, such as special vehicles or ships.

The whole structure of the rain gauge is made of metal parts without rust, the inner wall should be smooth and round, the edge of the water bearing device should be free of burr or bruit and other defects, the shape is beautiful and elegant, the weather resistance is good, and the service life is longer. The shell of a common rain gauge is a metal cylinder, divided into two sections. The upper section is a water funnel with a diameter of 20 centimeters. In order to prevent rain splashing and maintain the area and shape of the container mouth, the mouth of the cylinder is made of hard copper with a blade shaped like straight inside and oblique outside. Place a water bottle in the lower section cylinder to collect rainwater. To measure, pour rainwater into a special rain cup to read the precipitation in millimeters. In the snowfall season, the storage bottle is taken out and replaced with a cylinder without funnel. The snowflakes can be collected directly in the rain-measuring cylinder and read after the snow melts. The snow can also be weighed and converted into millimeters according to the area of the cylinder. Read additional info at rikasensor.com.
