Magnesium effectively reduces PONV
Effects of intra-operative magnesium sulfate infusion on orthognathic surgery: A prospective and randomized controlled trial.
Moderate relevance due to context
We conducted a study to discover how magnesium sulfate affects nausea during orthognathic surgery. In this research, we divided 75 adult patients into two groups: one group received magnesium sulfate, while the other received a placebo saline solution.

We discovered that those who received magnesium experienced significantly less postoperative nausea and vomiting (PONV) compared to the control group. Specifically, at two hours post-surgery, patients in the magnesium group reported less severe PONV.

Additionally, this group also had lower requirements for remifentanil, a pain reliever, indicating that magnesium not only helps with nausea but may also play a role in overall pain management during recovery. The magnesium levels in the blood after surgery were notably higher in the magnesium group, further supporting its effectiveness.

This research suggests that incorporating magnesium sulfate into treatment protocols during orthognathic surgeries can greatly enhance patient comfort by minimizing nausea and improving pain control.

Zinc treatment reduces nausea risk
Randomized, multicenter, active-controlled open-label study of NPC-25, zinc histidine hydrate, (non-inferiority to NOBELZIN™, zinc acetate dihydrate) for patients with hypozincemia.
Moderate relevance to nausea aspect
We conducted a study to evaluate how effective NPC-25, a new form of zinc, is compared to a well-known treatment, NOBELZIN™, for patients with low zinc levels. Participants in this trial had their zinc levels checked and were grouped to receive either NPC-25 or NOBELZIN™.

For a period of up to 24 weeks, we aimed to maintain their zinc levels within a specific target range while closely monitoring for side effects. One of our main goals was to see if NPC-25 could maintain these target zinc levels similarly to NOBELZIN™.

Our findings revealed that NPC-25 was indeed non-inferior to NOBELZIN™, meaning it worked just as well. Importantly, we also observed that those taking NPC-25 reported fewer digestive issues, like nausea and vomiting. This suggests that while both treatments were effective, NPC-25 might be the gentler option.

Zinc treatment in hypozincemia study
Post-marketing surveillance of zinc acetate dihydrate for hypozincemia in Japan.
Limited insight on nausea specifically
We explored the impact of zinc acetate dihydrate on several symptoms, including nausea, through a comprehensive study that assessed its safety and effectiveness for treating hypozincemia over a 52-week period. From the data collected, we observed an overall adverse reaction rate of 9.4%, with nausea reported in 1.4% of patients.

Despite nausea being a concern, the benefit of zinc acetate dihydrate for other indications was notable, with an efficacy rate of 83%. For patients experiencing symptoms such as pressure ulcers or stomatitis, the effectiveness was strikingly high. However, the specific effect of zinc on nausea is not definitively isolated within the study results, making it hard to gauge its direct and unique benefits.

In essence, while zinc acetate dihydrate shows promise for a variety of symptoms, including nausea, the evidence does not conclusively highlight its effectiveness for this particular issue on its own. Overall, it appears that zinc treatment can contribute positively to addressing several related health problems.

Nausea persisted
My mother ordered these supplements but began complaining of nausea after taking them as instructed—three tablets a day before bedtime. I refrained from taking them for a month to determine if they caused her nausea. When she resumed taking them, the same symptoms occurred, including stomach pain. Ultimately, these supplements were unsuitable for her.

Low opioids improve postoperative comfort
Are There Any Advantages of the Low Opioid Anaesthesia and Non-Opioid Postoperative Analgesia Protocol: A Clinical Observational Study.
Magnesium's impact on nausea unclear
We explored the effects of a low-opioid anesthesia (LOA) protocol during laparoscopic cholecystectomy and its impact on nausea, vomiting, and pain control. In our study, we compared 40 patients who received LOA, which included magnesium sulfate, with another 40 patients who were given standard opioid-based anesthesia.

While our findings showed that the LOA protocol was more effective in reducing nausea and vomiting compared to traditional opioid analgesia, we didn’t isolate magnesium’s specific role in this improvement. This limitation makes it challenging to determine just how much magnesium alone contributes to reducing nausea.

Nevertheless, the study suggests that using a low-opioid method can enhance patient comfort in the postoperative period. Overall, we found that incorporating non-opioid analgesia and the LOA strategy should be considered more widely in surgical practices.

Magnesium's role in nausea unclear
Analgesic Effects of Preoperative Combination of Oral Pregabalin and Intravenous Magnesium Sulfate on Postoperative Pain in Patients Undergoing Posterolateral Spinal Fusion Surgery: A 4-arm, Randomized, Double-blind, Placebo-controlled Trial.
Not definitive for nausea relief
We conducted a thorough investigation into how combining oral pregabalin and intravenous magnesium sulfate influences nausea in patients undergoing a specific type of spine surgery. In a well-structured trial, 104 participants were randomly assigned to one of four groups, where some received magnesium sulfate with pregabalin, while others received either a placebo or just one of the drugs.

Our primary focus was on how much morphine the patients needed on the first day after surgery, which gives us insight into their pain levels. While we noted the overall benefits of combining these two non-opioid treatments for pain relief, the study did mention postoperative nausea and vomiting as secondary outcomes. However, it's important to clarify that the findings did not specifically highlight any significant advantages of magnesium in reducing nausea when compared to the other treatments or placebos.

In essence, while we observed that the combination of magnesium sulfate and pregabalin effectively reduced opioid consumption and improved pain management post-surgery, it did not yield clear evidence pointing to magnesium's effectiveness specifically for alleviating nausea. This nuanced insight is valuable as we continue exploring the best strategies for managing multiple aspects of patient comfort during the recovery process.

Magnesium reduces post-operative nausea
Comparison of intravenous injection of magnesium sulfate and lidocaine effectiveness on the prevention of laryngospasm and analgesic requirement in tonsillectomy.
Consideration of magnesium's effects
In our exploration of how magnesium treatment influences nausea, we conducted a double-blind clinical trial with 62 children undergoing tonsillectomy. Participants were divided into two groups, where one received magnesium sulfate and the other lidocaine shortly after intubation.

We observed that while both medications were used, magnesium sulfate appeared to offer benefits over lidocaine. Notably, the group receiving magnesium experienced a significantly lower rate of nausea and vomiting compared to those treated with lidocaine. This points to magnesium's potential effectiveness in managing post-operative nausea.

However, it’s essential to note that our study did not find any significant difference in terms of laryngospasm incidence between the two groups. Overall, magnesium sulfate showcased an advantage with fewer instances of nausea and other distressing symptoms, suggesting its role as a valuable option for patient care in similar surgical scenarios.
