Effect of heparin sodium on postoperative inflammation after adult cataract surgery

To evaluate the effect of use of ringer lactate solution supplemented with heparin sodium in patients undergoing cataract surgery.In a prospective, double-blind, interventional study, 200 patients were included and were randomized to undergo cataract surgery using ringer lactate solution with or without 10 IU/ml heparin. All patients underwent phacoemulsification with hydrophobic acrylic foldable intraocular lens (IOL) implantation. The severity of anterior chamber inflammation and amount of pigment deposition of IOL was assessed by slit lamp biomicroscopy on day 1, 7, 28 and after 8 weeks postoperatively. Mean age in treatment and control group was 63.0± 11.5 years and 65.1±12.7 years respectively. A significant reduction in the severity of inflammatory cellular activity (p=0.001), flare (p=0.001) and pigment deposition on IOL (p=0.001) was noted on day 1 in the heparin treated group compared to the control group. However, no significant difference was observed in the amount of inflammatory activity as well as IOL pigment deposition beyond 1 week postoperatively. The inflammatory activity resolved almost completely in both the groups by the end of 8 weeks postoperatively. : Our study showed the beneficial effect of addition of heparin to irrigating solution during cataract surgery. Heparin treated eyes demonstrated a reduction in the early postoperative inflammation and IOL pigment deposition. The anti-inflammatory effect was observed in the early postoperative period.

Comparison between Glucose Containing Solution D2.5% and Ringer Lactate as a Maintenance Fluid Management in Infants Undergoing Inguinal Hernia Repair

Background Infants and neonates are at particular risk of hypoglycemia when suffering from sepsis, asphyxia and hypothermia. A prospective study showed that up to 20% of preterm infants who were ready for discharge were still at risk of hypoglycemia when a feed was delayed. In contrast, surgery and critical illness may cause hyperglycemia. Objectives The aim of this study is to Assessment of glucose containing solutions 2.5 % as a maintenance fluid management intra operative in infants undergoing hernia repair as regard hyperglycemia and hypoglycemia. Patients and Methods The study was conducted on 100 randomly chosen patients aged from 28 days to 1 year, American Society of Anesthesiologists (ASA) class I scheduled for elective open inguinal hernia repair in Ain Shams University Hospitals after approval of the medical ethical committee. They were allocated in two groups of 50 patients each: Ringer lactate Group: patients received ringer lactate as maintenance fluid therapy according to body weight, glucose containing solution: patients received glucose containing solution 2.5% as maintenance fluid therapy according to body weight. Results The results of the study revealed that 12% of patients receiving glucose containing solution 2.5 % had simple hyperglycemia with no hypoglycemic patients recorded while the other group with ringer lactate 2% of patients had simple hyperglycemia and 4% of patients had hypoglycemia . Conclusion The usage of glucose containing solution 2.5% remained controversial, in this study we compared glucose 2.5 % in normal saline 0,9 % to ringer lactate and the results didn’t put a final decision to the usage of glucose containing solutions as The results of the study revealed that 12% of patients receiving glucose containing solution 2.5 % had simple hyperglycemia with no hypoglycemic patients recorded while the other group with ringer lactate 2% of patients had simple hyperglycemia and 4% of patients had hypoglycemia.

Impact of Fluid Resuscitation Regimes in Relative Risk of Mortality in Burned Patients

Background; Some studies have supported the opinion that patients who get greater volumes of resuscitation fluids are at a higher chance of edema, complications, and probably bad outcomes. In the results of the International Society of Burn Injuries approximately half (49.5%) added colloid before 24h. This study aims to analyze the relative risk for mortality comparing resuscitation in the first 24 hours with Parkland and resuscitation with the use of Colloids. Material and Methods; This was an observational prospective cohort study conducted in the Service of Burns of the University Hospital Centre "Mother Teresa" in Tirana (UHCT), Albania. The study includes adult patients with critical burns > 40% TBSA, hospitalized in the Intensive Care Unit of the service during the period 2014 to 2019. Resuscitation in the first 24 hours is done with Ringer Lactate according to Parkland and with Ringer Lactate with the addition of colloids after 12 hours. Results; The data for organ dysfunction and organ insufficiency were the same in the two groups without statistical significance. Mortality in the RL group was 48% (24 deaths of 50 patients) while in the RL + Colloid rehydrated group was 46% (23 deaths of 50 patients). Patients which have 40-60% burns and are rehydrated with RL + Colloids have a risk of death 0.4 times less than those rehydrated with RL. Conclusions; Resuscitation with Ringer lactate and Colloids in the first 24 hours of thermal damage is a rehydration alternative for the treatment of burn shock. This therapy especially helps patients with major burns > 40% TBSA who during rehydration require large amounts of fluids and are associated with severe plasma hypoalbuminemia. Number Need to Treat (NNT benefit) is 10 so 1 in 10 patients can benefit in lowering the risk of death with RL + Colloid rehydration.

Effect of Woolen Cloth to Maintain Temperature 39°C of Crystaloid Fluid Ringer Lactate at Room Temperature 18°C

Fluid resuscitation with 39ᵒC is one of the main therapies for hypovolemic (hemorrhagic) shock patients to prevent complications. In this time, we already have tools to keep the fluid warm, but not all health services have these tools. To find out the effectiveness of using woolen cloth against the temperature of Ringer Lactate 39°C crystalloid fluid at room temperature 18°C. This study used a pre-experimental method, with a static group comparison approach, with 4 Ringer Lactate liquid samples divided into 2 groups, namely groups using wool cloth and those not using woolen cloth. Data collected through observation sheets. Data analyzed using the Mann Whitney test. With this p value (0.00001) <α (0.05), it can be concluded that there is a significant difference between the use of woolen cloth and those that do not use woolen cloth. The woolen cloth is effective to slow down the decrease in temperature of the crystalloid liquid Ringer Lactate 39ᵒC at room temperature 18ᵒC. The difference in temperature changes in the Ringer Lactate crystalloid fluid is influenced by several things including humidity, ambient temperature, and additional material used.

Improved Corrosion Resistance of Magnesium Alloy AZ31 in Ringer Lactate by Bilayer Anodic Film/Beeswax–Colophony

A bilayer anodic film/beeswax–colophony is proposed for improving the corrosion resistance of magnesium alloy surface. The bilayer was synthesized on the AZ31 alloy by anodization and subsequent dip coating, and the corrosion behavior was investigated by electrochemical measurements and weight loss test in Ringer lactate at 37 °C. The bilayer improved the electrochemical corrosion resistance by four orders of magnitude, as demonstrated by ~104 times lower corrosion current density in the polarization curves and ~104 higher film resistance in the impedance spectra. The tremendous surface area of the porous anodic film led to a strong attachment of the topcoat beeswax–colophony. Most of the coating remained attached to the surface after 14 days soaking in Ringer lactate. A few small blisters developed under the bilayer contributed to the low mass loss of 0.07 mg/cm2/day compared to the bare substrate, with an average loss rate of 0.25 mg/cm2/day. Local detachment of topcoat layer exposed the underlying anodic film that triggered the deposition of Ca and further nucleation of the Ca–P compound on the surface. The existence of a Ca−P compound with a Ca/P ratio of 1.68 indicated the ability of the bilayer to promote the formation of bone mineral apatite.

STUDY OF HARDNESS AND CORROSION RATE OF COPPER IONS IRRADIATED Mg–Al–Zn ALLOY IN RINGER LACTATE SOLUTION

In this work, the surface properties of Mg–Al–Zn (AZ91D) alloy such as surface morphology, hardness and electrochemical corrosion were studied after copper ions (Cu[Formula: see text] irradiation at different energies (0.8, 1.5, 2.5 and 3.5[Formula: see text]MeV) while keeping the ion dose constant at [Formula: see text] ions/cm2. The morphological features of irradiated samples showed defects composed of ejected material from the alloy surface that became more significant at 3.5[Formula: see text]MeV. The Vickers hardness was increased with increase of the Cu[Formula: see text] energy. The electrochemical testing of the samples was conducted in a Ringer Lactate solution. The potentiodynamic polarization results revealed anomalous changes in the corrosion rate of the Mg alloy with increase of the Cu[Formula: see text] energy. The corrosion rate was considerably decreased with increase of the Cu[Formula: see text] energy to 3.5[Formula: see text]MeV. These changes were associated with the surface defects and passive film formation on the alloy surface.
